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.
