Solution

Dear Student,
we know ,
pH = − log₁₀[ H₃O⁺]
pH = 2.32
∴ 2.32 = − log₁₀[ H₃O⁺]
[ H₃O⁺] = 10^-2.32 = 0.004786 =4.786 * 10^-3
pH + pOH = 14
pOH = 14 - pH == 14 - 2.32
∴ pOH = 11.68
now again,
pOH = - log₁₀[OH^-]
11.68 = -log₁₀[OH^-]
∴ [OH]^- = 10^-11.68 =2.1 10^-12
Concentration of [ H₃O⁺] = 4.786 10^-3M and [OH]- = 2.1 *10^-12 M
