Compared to a Solution of PH 9, a Solution of PH

Question

Compared to a solution of pH 9, a solution of pH 7 _______.
A) has a higher pH
B) has no OH- ions
C) is more basic
D) has more H+ ions

Accepted Answer

A solution with a pH of 7 has more H+ ions compared to a solution with a pH of 9, because the pH scale is logarithmic, and a lower pH indicates a higher concentration of hydrogen ions.
