On the pH scale,as the value moves from 14 toward 7,the concentration of hydroxide ions decreases.

Question

Quizplus · Accepted Answer

As the pH scale moves towards 7, the concentration of hydrogen ions increases and the concentration of hydroxide ions decreases. This is because pH is a measure of the acidity of a substance, and as acidity increases, the concentration of hydrogen ions increases while the concentration of hydroxide ions decreases. At a neutral pH of 7, the concentration of hydrogen and hydroxide ions are equal.
