Question 10 • Chemistry A.1 - F26 - Jacob Metsker

A substance with a high [H+ ] would likely have which additional characteristics?

Answer
A
a high [OH– ] and a high pOH
B
a low [OH– ] and a high pOH
C
a high [OH– ] and a low pOH
D
a low [OH– ] and a low pOH

Explanation

Water’s ion product means that as the hydrogen ion concentration [H+] increases, the hydroxide ion concentration [OH−] decreases. A lower [OH−] corresponds to a higher pOH because pOH = −log[OH−]. Therefore, the substance has a low [OH−] and a high pOH, as choice B states.
