...We recently did two labs where we were given the task of observing single-replacement and double-replacement reactions. This paper has background information on the different types of chemical reactions, as well as the chemistry behind the two reactions we observed in lab. A chemical reaction is a process that is characterized by a chemical change in which the reactants (starting products) are different from the products. Chemical reactions involve the breaking of old bonds and the formation of new bonds. They can result in the formation of precipitates, changes in color, production or absorption of heat, or formation of gas bubbles. Chemical reactions can be placed in the following five categories: (i) synthesis (ii) decomposition...

...Color Reactions of Protein Casein Abstract In this experiment different kinds of processes were done to isolate the different kinds of proteins. The protein casein was extracted from skimmed milk through isoelectric precipitation, albumin was also extracted from skimmed milk through heat denaturation, gluten was isolated from wheat flour through difference in solubility, and myoglobin from beef meat through salting out or salt-induced precipitation. The main objective of the qualitative color reaction of the proteins is to analyze the chemical groups present in the protein and explain the principle involved in each test. Biuret Test, Ninhydrin Test, Xanthoproteic Test, Millon’s Test, Hopkins-Cole Test, Sakaguchi Test, Nitroprusside Test, Fohl’s Test, Test for Amides, and Pauly Test were the different tests that were performed. Each test corresponds to the different reagents that were used. In the different tests performed, positive and negative results are gathered that indicates the presence or absence of a particular amino acid in the protein. Introduction Proteins are probably the most important class of biochemical molecules, although of course lipids and carbohydrates are also essential for life. Proteins are the basis for the major structural components of animal and human tissue. Proteins are natural polymer molecules consisting of amino acid units. The number of amino acids in proteins may range from two to several thousand.[3]Biologically active proteins...

...dye, methyl orange. Methyl orange is a dye produced from a synthesis reaction between diazonium ions and aromatic structures. Dyes have basic structure of Aromatic N+N-aromatic, azo group. methyl orange was synthesized by coupling reaction between diazonium ion and N,N-dimethyl aniline under basic condition. Diazonium ion created from sulfanillic acid monohydrate and N,N-dimethyl aniline under basic condition. Basicity was tested with pH paper after adding sodium hydroxide which resulted in light blue color, representing pH value of 10. Product yield was calculated to 71.53% with percent error of 28.46% so it was determined methyl orange was fairly produced. Introduction Methyl orange synthesis is diazo coupling reaction between the diazonium sale of sulfanilic acid and N,N-dimethylaniline. The initial product gained through coupling reaction is red acid form of methyl orange and this later turned to orange sodium salt, called methyl orange. Dyes are used to give colors to fabrics and Chromophores, functional groups that absorb light, give color to these dyes. The most common chromophores are azo, nitro, and carbon groups. The method of diazotiation is dependent on how basic and soluble the amine being coupled is. As sulfanilic acid is insoluble in acid, sulfanilic acid is dissolved in a basic solution. Primary aromatic amines can be directly diazotized but amines with sulfuric or carboxylic acid group is diazotized by dissolving the amine in dilute acid or water. Weakly...

...It is possible that some residue of the product could be stuck on them when we were transferring the product from filter paper into the beaker for weighing purposes. It is also possible that there are more residues left in the Erlenmeyer flask when the mixture was poured into the beaker. This causes the mass of salicylic acid in the Erlenmeyer flask and the beaker to vary. There is lesser amount of salicylic acid in the beaker; hence the mass of crystallized aspirin obtained toward the end of the experiment decreases, the percentage yield of the synthesis will be low. The amount of product lost during the experiment is...

...to identify the five mystery powders given to us which we were similar in appearance and to check their solubility and reactivity with water, vinegar and iodine. The objective was also to record information as accurate as possible and also to make observations in the reactions of five mystery powders with water, vinegar and iodine. Hypothesis- if we are using all the household mystery powders them they should all dissolve in water because I think all the household powders are soluble in water. Background information- we were given five different mystery household powders. So, as being different powders their physical and chemical properties will also be different such as some of them will react to water, some will react to vinegar and some to iodine. 1. To ensure that the data is correct all of us the group members did our recordings whatever we saw or observe and then checked it with all of the group members. 2. We also did all the tests one by one first with water, second with vinegar and then with iodine. I thought that if sodium bicarbonate reacts with vinegar then it will also react with iodine which wasn’t true. It reacted only with vinegar. 3. From our observations we used solubility and litmus paper to distinguish one [powder from another. 4. For most of this lab we used qualitative observations because at first before even starting the lab we looked at the unknown powders, potato, tums to see their color, texture, smell which are the qualities. Even during the...

...Abstract Alcohol is an organic compound group that contains OH, meaning a hydroxyl, which is a functional group. Alcohols contain various properties such as boiling point, which is much higher than its parent hydrocarbon due to polarity and hydrogen bonding. They are soluble in water, due to this as the alcohol chain increases the solubility of water will decrease which shows of an inversely proportional relationship. Their chemical properties consist of combustion, as this is true because alcohols are able to burn because the end product they produce is water and carbon dioxide. A very obvious reaction they undergo is dehydration of course since they break down and produce water. In this lab, three different types of alcohols are evaluated...

...ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24, 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in the other assays. These variables included a boiled, frozen and then thawed, and frozen potato extract and dH2O instead of the potato extract. It was noted that the temperature and or way the potato extract was prepared effects how the enzyme with the potato will react. Therefore the results of each assay varied, suggesting there is more than one way that a catalyzed reaction can occur. Introduction: (Burmania) The main purpose for this experiment was to explore how an enzyme catalase caused a reaction to catalyze through doing various assays using potato extracts. Enzymes are catalysts that are crucial in helping to speed up reactions, and catalase is a common enzyme found in almost every living organism that is exposed to oxygen. For this experiment, potatoes were used because they were previously known to have significant catalase activity. The potato catalase was mixed with hydrogen peroxide because the catalase helps to breakdown the hydrogen peroxide which helps determine how long a paper disk takes to float...

...laboratory synthesis, I hope to gain a better understanding of the reaction concepts governing Diels- Alder chemistry. Theory: The Diels-Alder reaction is a cycloaddition, chemical reaction that occurs between a conjugated diene, a molecule with two alternating double bonds, and dienophile, an alkene, to form rings and bicyclic compounds. Because it involves the interaction of four π electrons that are supplied by the diene and the two π electrons supplied by the dienophile, the Diels-Alder reaction is often called [4 + 2] cycloaddition. In the reaction, two new σ bonds are formed and one π bond is formed at the expense of two π bonds, which results in a cyclic product. The Diels-Alder reaction is a member of a larger class of reactions called pericylic reactions, which are reactions that take place in a single step, without intermediates and that involve the flow or redistribution of bonding electrons. The reaction proceeds through a cyclic transition state and is concerted, meaning bonds in the transition state are simultaneously made or broken. The Diels-Alder reaction is favored when the dienophile is the substituted with electron withdrawing groups such as nitriles, amines, and carbonyls and is especially favored when it reacts with dienes that contain electron-donating groups like alkyls and alkoxy on the diene. Diel’s Alder reactions have unique characteristics and requirements. Diels-Alder reactions are stereospecific, meaning cis-alkenes form cis-substituted products...
