Question

What happens when carbondioxide is compressed in water at high pressure?

Answer 1

When carbon dioxide is compressed in water at high pressure, carbon dioxide gas is dissolved in the liquid. When pressure is released, the carbon dioxide releases from the liquid as a gas.

According to the Henry's Law, It states that the amount of gas dissolved is proportional to the partial pressure.

Reaction- $H_{2}O\left(l\right)+C{O}_2\left(g\right)\stackrel{HighPressure}{\to }{H}_{2}C{O}_3\left(l\right)$
