Laboratory 3: Molarity Of Saline Solution
Note: Lab reports are to be completed by each student individually and in their own words
Data: Please write your observations about the appearance of the solution. 1. Normal Saline
Mass of NaCl: .9/100 ml x 100= .009 .009x100=.9
Observation: clear, completely dissolved 2. Nasal Irrigation Saline
Mass of NaCl: 1.1g
Mass of NaHCO3: .3g
Observation: clear, completely dissolved, when mixing I was a little cloudy 3. Nasal Irrigation Saline
29.7
Observation, This solution was very cloudy with bubbles, did not dissolve all the way

Results: 1. Determine the molar mass of NaCl. Show the workup.
Na= 23 plus C= 35 = 58 NaCl molecules
58g/m NaCl

2. Determine the molarity of the two solutions you prepared in terms of NaCl. Show the workup. (a) Normal Saline - Molarity of NaCl
M= .9 mole NaCl / 0.1 L solution= 9m NaCl

(b) Nasal Irrigation Saline - Molarity of NaCl
118ml = 0.118L
M= 1.1g/mole NaCl / 0.118L solution = 9.322 M NaCl

(c) Nasal Irrigation Saline - Molarity of NaHCO3 M= .3 mole NaHCO3 / o.118L = 2.54 M NaHCO3

3. The University of Wisconsin recommends that if stinging or burning occurs, than individuals should cut the amount of salt in half for the solution and decrease frequency of use to every other day. How does that affect the concentration of the solution?
When adding less salt it make the solution to become more dilute solution. This means the solution has less solute and more solvent.

4. Compare and contrast the solutions in terms of their sterility and potential uses.
Normal saline is a sterile solution to be used as I.V. flushes and to dilute medications, wound care, and rising of contacts. Nasal irrigation is often used to flush the nose and to clean out the sinus areas. this solution clear mucus out of the human nose.

5. Why should saline for irrigation never be used for intravenous uses?
This solution has too much sodium in it. This would cause all kinds of health problems, for example, high blood pressure. Too much sodium in the blood would cause all the cell to swell and burst.

6. If a nurse were to administer a Congestive Heart Failure Patient Hypertonic Saline (3%) instead of half-normal saline, what physiological effects do you think this would have on the patient?
If a nurse gives the patient hypertonic saline 8 percent. the patient would experience water retention, higher blood pressure, and swelling. Also it may cause the heart to burst if this patient retain to much sodium.

7. On average, one patient dies per month in a hospital in the US when a nurse gives the patient the wrong IV. Please discuss your knowledge of the different forms of IV’s and explain how this can be prevented.
I know where I work we use D5W for most sickle cell patients. This solution helps them get out of crisis, help them with dehydration, and help move the sickle red blood cells in the blood. When a patient come in with renal failure we slow down the rate and switch the fluids to 0.9 percent normal saline and lactated ringer. Whys to prevent giving the wrong fluids. Always do an assessment on the patient if the nurse has a problem call the doctor. For example, patient history to find out if they have any disorder the doctor might had miss. Next, check to make sure to have the right patient, right fluids, right dose, right time. Always check the mar before hanging any fluids.

8. What did you learn from this laboratory exercise? Summarize your conclusions in 10-12 sentences. Be specific in your answer.
What I have learned from this lesson. That are body uses salt or sodium and many ways. When we are sick or lose a lot of fluids for both ends mouth and anus. Our body needs water and sodium to imbalance are PH levels back to normal. I also learned that there are many different types of I.V. solution for different medical issues. I learned that If a person has a really bad sinus problem. They can use salt, water, and baking soda to make a solution call nasal irrigation saline. This solution will help them clean out their nasal cavity to get rid of allergens in the pass way. I learned how to measure tsp of salt and baking soda to convert them in to mass. Then, using the information to get mole, mass, and molarity.

1. Visit your local Grocery, SuperCenter or auto parts store to complete this week's discussion post.
Today I went to Kroger. I found 1. CH3CH(OH)CO2H Lactic acid is the acid in Yoplait strawberry yogurt.
2. C12H22O11 is acid in Kroger brand sugar.
3.
Find 3 products in 3 different sections (or aisles) of the store that contain an acid(s) or a base(s). Start with common products you use regularly. Provide the name of the store you visited, the name of the product you observed and the specific acid (or base) identified. You will be surprised at how many everyday products contain these compounds.

This is an example of what I want: At Walmart, I found that NaOH is the base in Mizani Regular strength hair relaxer.

2. Find an article or video that helped you understand oxidation-reduction. (a) Post the link to help your classmates in their understanding. (b) Show an example of an oxidation-reduction reaction and identify each component
