Answer : The pH of a solution is, 7.28

Solution : Given,

Concentration of hydronium ion, $H_3O^+$ = $5.2\times 10^{-8}M$

pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.

$pH=-\log [H_3O^+]$

Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.

$pH=-\log (5.2\times 10^{-8})=7.28$

Therefore, the pH of a solution is, 7.28
