If the pH of a solution is 10, what is the hydroxide ion concentration?

Question

Quizplus · Accepted Answer

The pH scale is inversely related to the concentration of hydrogen ions (H+) in a solution, and directly related to the concentration of hydroxide ions (OH-). A pH of 10 means the solution is basic. The relationship between pH and pOH is given by the equation pH + pOH = 14. Therefore, if the pH is 10, the pOH is 4. The concentration of hydroxide ions can be found using the formula [OH-] = 10^(-pOH), which gives [OH-] = 10^(-4) M or 1 × 10^-4 M.
