Which solution has a hydronium ion concentration of 1.00 x 10-5 M?A Solution with a PH of 4, 7, 3, or 5

Sagot :

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]
