Should rainwater containing CO2 come into contact with limestone what will form as a result?
Calcium Hydrogen Carbonate

How do pH levels of the sea stay stable?
The pH of the sea remains constants due to a buffering action of dissolved carbon dioxide, hydrogen carbonate and carbonate ions
3 of 5
How will burning fossil fuels have an effect on pH levels of the sea?
There will be more CO2 to react with the water forming more acidic solution in the sea thus lowering pH levels
4 of 5
What is a buffer solution?
A buffer solution is one that resists a change in pH when contaminated with small amounts of acid or alkali.
