Question

If the concentration of hydrogen ion in a sample of soft drink is$3.8\times {10}^{–3}\mathrm{m}$.What will be its $\mathrm{pH}$?

• A. 2.42
• B. 2.82
• C. 3.08
• D. None Of These

Answer 1

The correct option is A

2.42

Explanation:

Step 1: Analyzing the given data:

According to the data provided; the hydrogen ion concentration is given as $=3.8\times {10}^{–3}\mathrm{m}.$

Step 2: Calculation of pH of soft drink

The pH value of the given soft drink can be calculated as;

$$\begin{gathered} \mathrm{pH}=-\log \left({\mathrm{H}}^{+}\right) \\ \mathrm{pH}=-\log \left(3.8\times {10}^{–3}\right) \\ \mathrm{pH}=2.42 \end{gathered}$$

Therefore, the pH value of the sample of soft drink is calculated to be $2.42.$
