Answer:

* [tex]pH=4.37[/tex]

* The solution is acidic since the pH is below 7.

Explanation:

Hello,

In this case, we can mathematically define the pH by:

[tex]pH=-log([H_3O^+])[/tex]

Thus, for the given hydronium concentration we simply compute the pH:

[tex]pH=-log(4.3x10^{-5})=4.37[/tex]

Thereby, we conclude the solution is acidic due to the fact that the pH is below 7 which is the neutral point and above it the solutions are basic.

Regards.
