Carbon dioxide is soluble in water and forms carbonic acid, biocarbonate ions, and carbonate ions. If a mineral has a PZC (point zero change) of 8.9, what species will adsorb at pH 3? What about pH 9.1? Explain your reasoning.
Homework Answers
PZC is defined the pH when the electrical surface charge on surface of molecules is zero.
If pH is less then PZC , the medium will be acidic and vice
versa.

10.a. Carbon dioxide produced during cellular respiration can combine with water to form carbonic acid. Bromophenol blue can be used to detect changes in pH. It will remain blue in a basic solution or turn yellow in color in the presence of an acid. you exhaled through a straw into a beaker filled with water and then tested the water with Bromophenol blue, would you predict a change in color, yes or no? REVIEW b. Explain your answer.

Carbon dioxide dissolves in water to form carbonic acid, which
is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium
equation The acid dissociation constants listed in most standard
reference texts for carbonic acid actually apply to dissolved CO2.
For a CO2 partial pressure of 1.8×10–4 bar in the atmosphere, what
is the pH of water in equilibrium with the atmosphere? (For
carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).
