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

ACa2+ ions as the only positive ions in solution
BH3O+ ions as the only positive ions in solution
COH– ions as the only negative ions in solution
DH– ions as the only negative ions in solution

Verified Answer :

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

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)
