CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds, and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined, resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt containing

Post-Lab Questions 1) a. The relationship of the pH to the ratio of concentrations of the conjugate base to conjugate acid is based on the Henderson Hasselbalch equation, pH=pKA+ log([conjugate base] / [conjugate acid]). The graph of the relationship between pH and this ratio showed to increase rapidly at first, and then more slowly. This shows a logarithmic curve and that the relationship of the ratio is a logarithmic function of pH. When pH was graphed with the log of this ratio, the graph became

School of Nursing, Midwifery and Interprofessional Studies. With reference to acid-base balance explore the role of the respiratory system in maintaining blood pH? ‘We live and die at the cellular level’ (Reid, 2011). Homeostasis is crucial for normal cellular function. Acid-base homeostasis is the part of human homeostasis and refers to the balance between the production and elimination of H+ hydrogen ions (pH) within the body fluids (William, Simpkins, 2001, p.236). Metabolic reactions

molecules containing a group of atoms called an ester can be hydrolyzed by water to form a –COOH group (carboxylic acid) and an HO-- group (alcohol) as follows: RCOOR’ + H2O ( RCOOH + HOR’ This reaction is spontaneous for almost all esters but can be very slow under typical conditions of temperature and pressure. The reaction occurs at a much faster rate if there is a significant amount of base (OH-) in the solution. In this lab experiment, the rate of this reaction will be studied using an ester called

The acid-base balance in the body largely depends on the hydrogen ion (H+) concentration. In general, high H+ makes the solution acidic with pH less than 7 while low H+ will make the solution basic or alkaline with pH higher than 7 (Lewis, 2013). Acidosis develops when the arterial pH drops below 7.35 while alkalosis develops when the arterial pH rises above 7.45 (Appel & Downs, 2008). The normal metabolic balance generally keeps the carbonic acid and bicarbonate ion to 1:

Acid-Base Balance Kelly Heffron Grand Canyon University NUR-614 September 16, 2015 Acid-Base Balance The acid base balance is a homeostatic process that aides the body in maintaining a pH in the arterial blood between 7.35-7.45 (Patient, 2015). The body works together through multi-systems to ensure that acidity or alkalinity never take over within the blood. The purpose of the following paper is define the classification of the acid-base balance, define the factors from the case study,
