Verified Answer :

PBCHEM

Answer : Option D) 9.90

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

pH = - log \([H^{+}]\)

Here, the concentration of \([H^{+}]\) = \(1.25 X 10^{-10} M\)

So, substituting this value in above formula;

we get pH = -log  \([ 1.25 X 10^{-10} M]\)

Therefore, pH = 9.90.

The pH of the solution is 9.90.

What is pH?

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 = \(\bold{-log ^[^H^+^]}\)

Given the concentration of H+ = \(1.25\times 10^-^1^0_\)

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

Thus, the pH of the solution is 9.90.
