Calculation of Hydrogen Ion Concentration from pH What is the H1 concentration of a solution with pH of (a) 3.82; (b) 6.52; (c) 11.11?

a) 1.5 x 10^-4

b) 3.2 x 10^-2

c) 7.76 x 10^-12

Explanation:

Since pH = - log (H+)

For A,

3.82 = - log (H+)

(H+) = Antilog (-3.82)

H+ = 1.5 x 10^-4

For B,

6.52 = - log (H+)

(H+) = Antilog (-6.52)

H+ = 3.2 x 10^-2

For C,

11.11 = - log (H+)

(H+) = Antilog (-11.11)

H+ = 7.76 x 10^-12

Thus, the hydrogen ion concentration of a, b and c are 1.5 x 10^-4, 3.2 x 10^-2, and 7.76 x 10^-12 respectively.
