Question

The pH of 0.1(M) H₂SO₄ in water is

• A. Is equal to one
• B. Is more than one
• C. Is less than one
• D. May be equal to or greater than or smaller than one depending upon temperature

Answer 1

Answer: (C)

Is less than one

Answer 2

H₂SO₄ ¾® H⁺ + $HSO_{4}^{–}$

$HSO_{4}^{–}$ $\rightleftarrows$H⁺ + $SO_{4}^{2–}$

In solution [H⁺] > 0.1(M), hence pH < 1
