A Solution with a PH of 6 Has ________ Times

Question

A solution with a pH of 6 has ________ times as many hydrogen ions as a solution with a pH of 8.
A) 1,000
B) 10
C) 100
D) 10,000
E) 100,000

Accepted Answer

The pH scale is logarithmic, meaning each whole number change on the scale represents a tenfold change in hydrogen ion concentration. A solution with a pH of 6 has 10^2 (or 100) times more hydrogen ions than a solution with a pH of 8.
