What is the [H+] of a solution with a pH of 9.40?
LiRa [457]

Answer:

a) 3.98 x 10^-10

Explanation:

Hello,

In this case, for the given pH, we can compute the concentration of hydronium by using the following formula:

pH=-log([H^+])

Hence, solving for the concentration of hydronium:

[H^+]=10^{-pH}=10^{-9.40}\\

[H^+]=3.98x10^{-10}M

Therefore, answer is a) 3.98 x 10^-10

Best regards.
