The PH = -Log[H⁺] for a Solution

question 1

Multiple Choice

The pH = -log[H⁺] for a solution. The pOH = -log[OH^-] for a solution. The pH and pOH are related, and their sum is equal to 14 (pH + pOH = 14) . If the concentration of a dilute solution of potassium hydroxide is 0.001 M, what is the pH of that solution?

• A) 7
• B) 3
• C) 11
• D) 2
