Along with the PH Scale, There Is the POH Scale

question 155

Multiple Choice

Along with the pH scale, there is the pOH scale, which indicates the level of "basicity" in a solution. Accordingly, pOH = -log[OH^-]. What is the sum of the pH and the pOH of a solution always equal to?

• A)the negative of the product of the hydronium and hydroxide ions
• B)the negative log of K_w, which is 14
• C)The sum would equal 7, since that would be neutral for pH and pOH.
• D)It is not constant because it depends on the acid/base solution in question.
