What is the pH of a cleaning solution with a [H+]=7.4x 10-6 M H+?

What is the pH of a cleaning solution with a [H+]=7.4x 10-6 M H+?

The pH of a cleaning solution with a [H+]=7.4x 10-6 M H+ is 5.13.

Calculating pH of the Cleaning Solution:

The pH of a solution is a measure of its acidity or alkalinity. It is defined as the negative logarithm of the concentration of hydrogen ions ([H+]) in the solution. In this case, the concentration of hydrogen ions is given as 7.4x 10-6 M.

Formula for pH Calculation:

The formula to calculate pH is pH = -log[H+].

Calculating pH:

Substitute the given [H+] value into the formula: pH = -log(7.4 x 10-6) = -log7.4 - log10^-6 = -5.13

Conclusion:

Therefore, the pH of the cleaning solution with [H+] =7.4x 10-6 M H+ is 5.13, which corresponds to option C in the provided choices.
