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?...

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.

is the pH of water in equilibrium with the atmosphere? (For
carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).
