Question

What are [H₃O⁺], [OH⁻], and pH in a solution with a pOH of 3.44?

[H₃O⁺] = ___× 10M

[OH⁻] = ____× 10M

pH = ____

Answer 1

Ans :

pH + pOH = 14

pH = 14 - pOH

= 14 - 3.44

= 10.56

[H3O+] = 10^-pH

= 10^-10.56

= 2.75 x 10^-11 M

[OH-] = 10^-pOH

= 10^-3.44

= 3.63 x 10^-4 M

pH = 10.56
