Answer:

pH = 7.14.

Step-by-step explanation:

Hello there!

In this case, since the pH of a solution is computed via the negative logarithm of the concentration of hydrogen ions:


pH=-log([H_3O^+])

Therefore, we plug in the given concentration to obtain:


pH=-log(7.2x10^(-8))\\\\pH=7.14

Which is a nearly-neutral solution.
