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

Question

Quizplus · Accepted Answer

As the value on the pH scale moves from 14 towards 7, the concentration of hydroxide ions actually decreases. At a pH of 7 (neutral), the concentrations of hydroxide and hydrogen ions are equal. As the pH moves towards acidic values (less than 7), the concentration of hydrogen ions increases and the concentration of hydroxide ions decreases. Conversely, as the pH moves towards basic values (greater than 7), the concentration of hydroxide ions increases and the concentration of hydrogen ions decreases.
