Answer:
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.
