Effects of altering the pressure in chemical equilibria

Simple experiments illustrate the effects of altering the pressureDecreasing pressure leads to less dissolved gas. The less carbon dioxide is dissolved, the higher the pH value of the solution is. This can be shown with a suitable indicator. |
