Answer:
The correct answer is 10.
Explanation:
The pH of a solution can be calculated by using the following formula:
[tex]pH = - \log_{10} [H^{+}][/tex] (1)
Where [tex][H^{+}][/tex] is the concentration of hydrogen ions in the solution.
If we know that solution D has a hydrogen ion concentration of [tex]1\times 10^{-10}[/tex], then the pH of the solution is:
[tex]pH = - \log_{10}(1\times 10^{-10})[/tex]
[tex]pH = 10[/tex]
Hence, the correct answer is 10.
