Question

In a solution the hydroxide ion concentration is 1 ✕ 10-12 M. What is the pH of the solution?

What is the pOH of the solution?
The above solution is

Answer 1

pH = 2 and pOH = 12

Step-by-step explanation:

Given [OH⁻] = 1 x 10⁻¹²M

pOH = -log[OH⁻] = -log(1 x 10⁻¹²) = - ( -12 ) = 12

pH + pOH = 14 => pH = 14 - pOH = 14 - 12 = 2
