# Compression of a liquid with a gas dissolved in it?

If I remember correctly you cannot compress a liquid, but I know you can compress a gas. (usually to the point it becomes a liquid then no further)

What happens if I were to compress soda water? A liquid with a gas trapped in it.

Would the gas escape the liquid, then compress? Or compress within the liquid?

This is actually more chemistry than physics: soda is carbonic acid, $H_2CO_3$, which decomposes under the equation $H_2CO_3(l)\iff H_2O(l)+CO_2(gas)\uparrow$. LeChatelier's principle (one of the variants of conservation of energy) states that a system placed under stress (like pressure) will shift towards the side that best relieves that stress.
