Question

What is the pH of solution D? (AP Chem)

Answer 1

Answer:

The correct answer is 10.

Explanation:

The pH of a solution can be calculated by using the following formula:

$pH = - \log_{10} [H^{+}]$ (1)

Where $[H^{+}]$ is the concentration of hydrogen ions in the solution.

If we know that solution D has a hydrogen ion concentration of $1\times 10^{-10}$, then the pH of the solution is:

$pH = - \log_{10}(1\times 10^{-10})$

$pH = 10$

Hence, the correct answer is 10.
