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).

1. Marble is calcium carbonate (CaCO3). Its reaction with hydrochloric acid is CaCO3 + 2HCl CaCl2 + CO2 + H2O What was the gas produced when marble reacted with HCl? Write chemical equations for the reactions of marble with two other acids. Do these reactions have anything in common? In light of your observations, speculate on the damage to marble statues and buildings caused by acid rain. 2. What generalization can you make about the effect of changing...

Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium equation CO2(gas)<------>CO2(aq) K=0.032 M*atm-1 The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved CO2. For a CO2 partial pressure of 3.1×10-4 atm in the atmosphere, what is the pH of water in equilibrium with the atmosphere?

Carbonated drinks contain carbonic acid. The carbonic acid is formed when excess CO2 gas is added to the drink and then the container is quickly capped to capture the excess gas. The CO2 gas reacts with the water to form carbonic acid. The equilibrium is easily disturbed by shaking the bottle. a. Observe an unopened carbonated drink container. Describe if the bottle can be squeezed or if it is hard. Are the bubbles present on the top of the liquid?...
