How do pH and pOH play into chemical equilibrium?

pH and pOH are important to consider when solving acid base equilibria. Because pH=-log[H3O+], if you are given the pH either initially or at equilibrium, you can use than to find the concentration of H3O at that instant. Using this, you can create an ICE table and solve for whatever the question asks. Same goes for basic reactions, just use pOH instead.

A high pH and a low pOH means that the resulting solution is basic. A low pH and a high pOH means that the resulting solution is acidic. pH and pOH values should add up to be 14.

Acids and bases in solution are examples of chemical equilibria. pH and pOH are measures of the molar concentration of H3O+ and OH- in a solution respectively.

Thank you for the response. Could someone show me an example of this problem in action. How would I use pH and pOH in an acid/base equilibrium problem?
