Question

Explain what is the definition of pH with the help of examples and equation that is used for calculating it.

Answer 1

pH:

1. The measurement of hydrogen ion concentration present in the solution is known as pH.
2. It is helpful in calculating the acidity and basicity of the solution.

The equation that is used for calculating pH:

The following equation is used for the calculation of pH,

$pH=-\log {\left[H\right]}^{+}$

1. It is simply the calculation of the negative log of the concentration of Hydrogen ions.
2. The pH of any solution depends on the concentration of Hydrogen ions.
3. pH is a temperature-independent quantity.

Uses of pH:

1. It is used the determination the nature of the solution.
2. It is also used in pharmacy for the preparation of drug dosage forms.
