What is the pH of a solution that has a hydroxide ion concentration of 1.0 x 10^-3 M?

What is the pH of a solution that has a hydroxide ion concentration of 1.0 x 10^-3 M?

Step 1: Identify the hydroxide ion concentration given in the problem, which is 1.0 x 10^-3 M.
Step 2: Use the formula for pOH, which is pOH = -log[OH-].
Step 3: Substitute the hydroxide ion concentration into the formula: pOH = -log(1.0 x 10^-3).
Step 4: Calculate the logarithm: -log(1.0 x 10^-3) equals 3.
Step 5: Now that you have pOH, use the relationship between pH and pOH: pH = 14 - pOH.
Step 6: Substitute the value of pOH into the equation: pH = 14 - 3.
Step 7: Calculate the final pH: 14 - 3 equals 11.
