A Water Solution with a PH of 7

Question

A water solution with a pH of 7 A) is an acid B) has equal numbers of OH^- and H⁺ ions C) is a base D) contains neither OH^- nor H⁺

Accepted Answer

A solution with pH of 7 is neutral, meaning that it has an equal concentration of H+ and OH- ions. This results in an equal concentration of water molecules (H2O), hydronium ions (H3O+), and hydroxide ions (OH-), which can be represented by the equilibrium equation: H2O = H+ + OH-. Therefore, the solution contains both OH^- and H⁺ ions in equal numbers.
