Answer

1.0 \times 10^{-14} Explanation 1. Identify the relationship In any aqueous solution, the product of the hydronium ion concentration [H_{3}O^{+}] and the hydroxide ion concentration [OH^{-}] is a constant at a given temperature. 2. State the formula **The formula is:** [H_{3}O^{+}][OH^{-}] = K_w, where K_w is the ion-product constant for water. 3. Provide the value at 25°C At 25°C, K_w = 1.0 \times 10^{-14}.
