Answer: the pH of this solution is 9.89 and the best option to answer the question is letter B.

Step-by-step explanation:

The question requires us to calculate the pH of a solution, given the hidrogen ion concentration of this solution (1.3 x 10^-10 M).

The pH of a solution can be defined as:

$pH=-log[H^+\rbrack$

where [H+] corresponds to the hidrogen ion concentration in solution.

Applying the value of [H+] given by the question to the equation above, we'll have:

$\begin{gathered} pH=-log(1.3*10^(-10)) \\ pH=9.89 \end{gathered}$

Therefore, the pH of this solution is 9.89 and the best option to answer the question is letter B.
