Multiple Choice QuestionWhen sodium hydroxide dissolves in water, what occurs that makes sodium hydroxide an Arrhenius base?Multiple choice question.It dissociates to form hydroxide ions.It ionizes to form hydrogen ions.It accepts hydrogen ions.It reacts with water to form hydroxide ions.
Solution
The correct answer is: It dissociates to form hydroxide ions.
Here's why:
-
Sodium hydroxide (NaOH) is a compound that when dissolved in water breaks down into sodium ions (Na+) and hydroxide ions (OH-).
-
This process is called dissociation.
-
According to the Arrhenius definition, a base is a substance that increases the concentration of hydroxide ions when dissolved in water.
-
Therefore, because sodium hydroxide increases the concentration of hydroxide ions in water due to its dissociation, it is considered an Arrhenius base.
So, the correct answer is "It dissociates to form hydroxide ions."
