What is the concentration of H+ ions with pOH of 9.72?

Answer 1

pOH + pH = 14

Since pOH = 9,72 then we can calculate pH:

9.72 + pH = 14

pH = 14 - 9.72

pH = 4.28

pH is defined by:

pH = -log[H⁺]

so, plugging in the pH:

4.28 = -log[H⁺]

-4.28 = log₁₀[H⁺]

10^-4.28 = [H⁺]

[H⁺] = 0.0000525 or 5.25 x 10^-5
