Question

At what pH does the hydroxide ion concentration of a solution equals the hydronium ion concentration?Group of answer choicespH =1pH = 7pH =14pH = 0

Answer 1

pH = 7

Step-by-step explanation

In a neutral solution, the hydrogen ion (H⁺) ion concentration and the hydroxyl ion (OH⁻) ion concentration are equal, and each is equal to 10⁻⁷. A pH of 7 is neutral.

This means that at pH = 7 the hydroxide ion concentration of a solution equals the hydronium ion concentration.
