Solution:
1. The statements about an acid not true-
e. An acid increase the concentration of hydroxide ion in solution.
Since an acid increase the concentration of proton in solution, hence above statement about an acid is not true.
Acids are-
* Proton doner
* HBr is an acid since it is proton doner.
* Acid increase hydronium ion in solution
