Question

Quizplus · Accepted Answer

Since potassium chloride dissociates into one potassium ion and one chloride ion in solution, the concentration of chloride ions is equivalent to the concentration of potassium chloride. Therefore, the concentration of chloride ions in a 0.193 M solution of potassium chloride is also 0.193 M.
