Question

A sample of Ca(OH)2 is considered to be an Arrhenius base because it dissolves in water to yield

Answer 1

The answer is C. Arrhenius bases increase the concentration of OH- in solution.

Answer 2

Answer : The correct option is, (C) $OH^-$ ions as the only negative ions in solution

Explanation :

According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion $(H^+)$ and a bases is a substance that ionizes in the water to give hydroxide ion $(OH^-)$.

A sample of $Ca(OH)_2$ is considered to be an Arrhenius base because when it dissolves in the water to yield $OH^-$ ions as the only negative ions in solution.

Hence, the correct option is, (C)
