Question

Which of the following expressions is valid at 25C?

A. [H+][OH-] = 1.0 x 10-14 M2

B. pH + pOH = 14

C. KaKb = Kw

D. All of these

science chemistry

Answer 1

Answer #1

pH = -log[H+]

pOH = -log[OH-]

pH + pOH = 14.00

At 25 °C the ionic product of Water

Kw = [H+][OH-] = 1.0 ×10^-14

Kw = Ka×Kb

Ka = acid dissociation constant

Kb = base dissociation constant

The given three expression are correct.

Hence the correct option is (D) All of these
