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?...

Carbonic acid present in the blood comes mainly from dissolved carbon dioxide (CO2). Dissolved carbon dioxide, CO2(aq), reacts with water to produce H2CO3. a) Write the equilibrium expression for this process. b) The equilibrium constant for this reaction is the hydration constant for CO2, Kh = [H2CO3]/[CO2(aq)] = 3.0 x 10−3 . Combine this equation with the expression you derived in 1.a) for the equilibrium expressions for the first ionization (controlled by Ka1) and rearrange to obtain the apparent equilibrium...

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).
