Question

Quizplus · Accepted Answer

Hydrochloric acid (HCl) is a strong, monoprotic acid. Potassium hydroxide (KOH) is a strong base that contains one hydroxide anion per molecule. The concentrations and volumes of these solutions are related by the formula (Molarity₁)(Volume₁) = (Molarity₂)(Volume₂). Entering the variables into this equation gives (.250 M)(Volume₁) = (.500 M)(1.25 liters). Solve for Volume1 to find the correct answer, 2.5 liters.
