27 What can be explained by the Arrhenius theory?(1) the behavior of many acids and bases

(2) the effect of stress on a phase equilibrium

(3) the operation of an electrochemical cell

(4) the spontaneous decay of some nuclei

Verified Answer :

There are several different things that can be explained by the Arrhenius theory, but the best option from the list would be "the spontaneous decay of some nuclei".

Answer : The correct option is, (1) the behavior of many acids and bases

Explanation :

The Arrhenius theory sates that an acid is a type of substance that ionizes in the water to give the hydronium ion or hydrogen ion \((H^+)\) and a bases is a type of substance that ionizes in the water to give hydroxide ion \((OH^-)\).

Or we can say that,

A substance that increases the hydroxide ion concentration of a solution is known as an Arrhenius base.

A substance that increases the hydrogen ion concentration of a solution is known as an Arrhenius acid.

Thus, the behavior of many acids and bases can be explained by the Arrhenius theory.

Hence, the correct option is, (1) the behavior of many acids and bases
