Question

Loss of CO2 in egg, _____________ the pH of egg whites

A. Increases
B. Decreases
C. Has no effect on
D. Stabilizes

Answer 1

Loss of CO2 in an egg increases the pH of the egg whites.

Step-by-step explanation:

Losing CO2 in an egg will increase the pH of the egg whites. When CO2 is lost, it decreases the concentration of carbonic acid (H2CO3) in the egg whites. Carbonic acid is a weak acid that dissociates into bicarbonate ions (HCO3-) and hydrogen ions (H+). With a decrease in carbonic acid, there is a decrease in hydrogen ions, which results in an increase in pH.
