Qualitatively, what happens to the hydroxide ion concentration if you decrease the hydronium ion concentration?

Question

Quizplus · Accepted Answer

When the concentration of hydronium ions (H₃O⁺) decreases in a solution, the concentration of hydroxide ions (OH⁻) increases to maintain the product of the concentrations of these ions at a constant value (Kw = [H₃O⁺][OH⁻] = 1.0 x 10⁻¹⁴ at 25°C), according to the principle of chemical equilibrium. This is because water dissociation is an equilibrium process, and decreasing the concentration of H₃O⁺ shifts the equilibrium towards more OH⁻ production to maintain the balance.
