Interpretation Introduction

Interpretation:

The acidity of the solution based only on pH of the solution along with any example of negative or zero pH is to be explained.

Concept introduction:

Hydronium ion concentration is used to decide the acidity of a solution. An increase in the concentration of hydronium ion increases the acidity of a solution.

pH is the measure of acidity of a solution and is dependent on the hydronium ion concentration and temperature of the solution

The formula to calculate the pH of the solution from the concentration of hydrogen ions is:

pH=−log[H3O+] …… (1)

At 25∘C, the pH of a neutral solution is 7.00, below which a solution is acidic and above which the solution is basic.
