Answer : Option D) 9.90

Explanation : The pH of the solution can be determined by the formula as

pH = - log [tex] [H^{+}] [/tex]

Here, the concentration of [tex] [H^{+}] [/tex] = [tex] 1.25 X 10^{-10} M [/tex]

So, substituting this value in above formula;

we get pH = -log [tex][ 1.25 X 10^{-10} M] [/tex]

Therefore, pH = 9.90.

The pH of the solution is 9.90.

pH defines as the potential of hydrogen, it is s scale used to determine acidity and basicity.

We can determine the pH of a solution by the given formula

pH = [tex]\bold{-log ^[^H^+^]}[/tex]

Given the concentration of H+ = [tex]1.25\times 10^-^1^0_[/tex]

We get [tex]\bold{-log ^[^1^.^2^5^\times^ 1^0^-^1^0^]}[/tex] = 9.90

Thus, the pH of the solution is 9.90.
