Calculate the pH and pOH of a solution given .0050  M solution of KOH.   pH = _____[A] pOH = _____[B]   Your answers should go no more than two places past the decimal point.

Which statement about the equilibrium constant is true? The value of Kc changes as product concentration changes. changes as reactant concentration changes. changes as temperature changes. never changes. changes over time.

The equilibrium constant, K, for the reaction shown below has a value 1.8 × 10–5.  Based on the value of the equilibrium constant, which statement is true? CH3COOH(aq) + H2O(ℓ) ⇌ H3O+(aq) + CH3COO–(aq) At equilibrium, the reactant concentrations will be higher than the product concentrations. At equilibrium, the product concentrations will be higher than the reactant concentrations. At equilibrium, the reactant and product concentrations will be equal. A general statement about the equilibrium cannot be determined based on the data given. The given value of K is incorrect because the equilibrium constant for all reactions at equilibrium must be 1.
