Question

The pH of a solution can be calculated from which of the following expressions?
a) pH = -log [OH^-]
b) pH = log [OH^-]
c) pH = -log [H^+]
d) pH = log [H +]

Answer 1

Answer:

(c) pH = -log [H^+]

Explanation:

pH defines the acidicity or basicity a solution.

pH also refers to hydrogen ion concentration and it is only applied to aqueous solution.

pH ranges from 0 to 14. A pH of 7 is neutral and a pH less than 7 is acidic while a pH higher than basic.
