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

First, we can find the pOH of the solution:
pOH = -log[OH⁻] = -log[0.001] = 3
Then we can use the pH + pOH = 14 equation to find the pH:
pH + pOH = 14
pH + 3 = 14
pH = 11

The PH = -Log[H⁺] for a Solution
