The concentration of hydrogen ion in any solution is 1 × 10^-4 gram mole/litre. Find out value of pH of this solution. Also state that this solution is acidic or basic.

Given:

Concentration of hydrogen ion = [H⁺] = 1 × 10^-4

To calculate the pH of this solution, apply the formula given below:

pH= -log [1 × 10^-4]

pH= -log [ -4 log 10]

pH= log 4

pH = 0.602

pH of the solution is 0.6. Hence it is an acidic solution (less than 7)
