Question

What is the solution to H30+ = 1.0 x 10-4 M

Answer 1

The pH of the solution is 4 and it is acidic.

Step-by-step explanation:

To calculate the pH knowing the concentration of H3O+, it is necessary to use the pH formula:

`\begin{gathered} pH=-log\lbrack H_3O^+\rbrack \\ pH=-log(1.0*10^(-4)) \\ pH=4 \end{gathered}`

So, the pH of the solution is 4. Since the pH value is less than 7, the solution is acidic.
