Answer
A solution with pH of 5.
Explanation
Given:
[H₃O⁺] = 1.00 x 10⁻⁵ M
To know the solution that has a hydronium ion concentration, [H₃O⁺] of 1.00 x 10⁻⁵ M, you need to calculate the pH of the solution using the formula given below:
[tex]pH=-log\left[H₃O⁺\right][/tex]Put [H₃O⁺] = 1.00 x 10⁻⁵ M into the pH formula:fof
[tex]\begin{gathered} pH=-log(1.00\times10⁻⁵M) \\ \\ pH=-(-5) \\ \\ pH=5 \end{gathered}[/tex]
