A Solution That Has a High Concentration of Hydroxide (OH-)Ions

Question

A solution that has a high concentration of hydroxide (OH-)ions
A)has a low pH.
B)has a high concentration of hydrogen (H+)ions too.
C)is a basic (alkaline)solution.
D)is a neutral solution.
E)is an acidic solution.

Accepted Answer

A high concentration of hydroxide ions indicates a basic (alkaline) solution, as hydroxide ions have a pH above 7. This solution would have a low concentration of hydrogen ions (H+), as these ions have a pH below 7. Therefore, options A, B, D and E are incorrect.
