This is roughly what occurs with CO2 in the oceans. I say roughly because there are other elements in the oceans and the temperatures are different in the upper and deep oceans.

2NaCl (salt) + H2O (water) + CO2 Na2CO3 + 2HCl 

The HCL is hydrochloric acid. It is what is acidifying the oceans. Now, there is nothing to say the changes will remain permanent.. That is not the case. HCL is ionic and interacts easily with the other molecules. When the CO2 density in the troposphere declines it can force the reverse reaction. The atmospheric air pressure works in this reaction as well. The molecules are 'active' differently at sea surface with 14.6 psi opposed to the deeper oceans where the pressures go up 'one atmosphere' every 33 feet down.

One atmosphere = 14.2 psi

There is nothing magical about 33 feet either. The pressure of the water can be felt immediately upon entering the water. At 33 feet a diver would finally be in water with pressure of an additional atmosphere, but, would be feeling increased pressure during the entire decent.
