The pH of a solution is 10. What is its OH - concentration

Answer: 1 x 10∧-4

Explanation:

In other for us to get the OH - concentration, we must first get the pOH.

pH + pOH = 14

pOH = 14 - pH; 14 - 10 = 4

From the formular for finding pOH, we know; pOH = - Log [ OH-]

∴ [ OH-] = Anti - log of 4

= 10∧-4 = 0.0001

= 1 x 10∧-4
