Question

A substance with a high pOH would likely have which of the following?
A low [H+ ] and a high pH
A low [OH– ] and a high pH
A high [OH– ] and a low pH
A high [H+ ] and a low pH

Answer 1

A high pOH means [OH–] is low and, since pH + pOH = 14, the pH is low — so the solution has a high [H+] and a low pH (option 4).
