Solution : Given,
Concentration of hydronium ion, =
pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.
Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.
Therefore, the pH of a solution is, 7.28
