What effect on a person's blood pH would you expect for each of these interventions or activites? Why?
Homework Answers
A ) PH decreases when breathing restricted due to higher level of CO2 dissolve in blood .Blood PH decreases due to carbonic acid formation.
B ) PH increases since bicarbonate is alkaline and is used to treat acidolysis.
C ) carbonate is basic it increases PH of blood so use as antacid.

Case Study Section 1 – pH Based on “The Case of the Mortified Mom: Acids, pH and Buffers” by Terry Platt (National Center for Case Study Teaching in Science) The Patient: Paramedics were called to the home of the Mathews family because their 3-year old daughter, Molly, had gotten into the medicine cabinet and consumed a large number of aspirin tablets. When the paramedics arrived Molly had vomited several times, with bits of undissolved tablets visible, but seemed sleepy, almost...

Acid precipitation can harm living organisms in rivers and streams, but some rivers are more vulnerable than others. Streams in the Adirondack Mountains, for example, were quickly acidified by acid precipitation in the 1970s and 80s, kiling local trout populations. But rivers that ran through a bed of limestone (calcium carbonate), like the Clark Fork River in Montana, were less affected. Part 8 of 10 What can explain the relative lack of effect of acid precipitation on the Clark Fork...

104 Homework 6 4. (15 points): Hemoglobin (Hb) is the main oxygen transport protein in the blood. Each hemoglobin molecule can transport four oxygen atoms at a time, one at each of its four iron-based binding sites. The binding of O2 to hemoglobin is a pH-dependent equilibrium, simplified as: Use Le Chatelier's Principle to answer the following questions: a) What form of hemoglobin, HbH" or Hb(Ojle, would be favored in the lungs? What form would be favored in the cells...

uns w une sent, ultimately decreasing the H concentration and increasing the pH. As you might expect, blood cycles from a pH of about 7.20 in respiring tissues to about 7.60 in the lungs. Why rebreathing CO2 prevents fainting during a panic attack Let's return to Harold, the man who was hyperventilating in this case. Given your understanding of pH, acid-base equilibria, and a little about the structure and function of hemoglobin, hopefully it is now clearer why rebreathing his...
