Interpretation Introduction

Interpretation:

The reason for the fact that distilled water has hydrogen ions and hydroxide ions but still it is neutral is to be explained.

Concept introduction:

The $\text{pH}$ value ranges from $0-14$. The substance that has $\text{pH}<7$ is considered as acidic whereas the substance that has $\text{pH}>\text{7}$ is considered as basic. The neutral $\text{pH}$ value is $7$. A general dissociation reaction of water is shown below.

${\text{H}}_2\text{O}\left(l\right)\to {\text{H}}^{+}\left(aq\right)+{\text{OH}}^{-}\left(aq\right)$
