Determine the [OH^-] concentration of a 0.741 M KOH solution at 25°C. A) 1.34 × 10^-13 M B) 1.34 × 10^-14 M C) 0.741 M D) 7.41 M E) none of the above

Question

Quizplus · Accepted Answer

KOH is a strong base that dissociates completely in water to form K+ and OH- ions. Therefore, the concentration of OH- ions in a 0.741 M KOH solution is the same as the concentration of the KOH solution itself, which is 0.741 M.
