What is the concentration (in M)of hydronium ions in a solution at 25.0 °C with pH = 4.153?

Question

Quizplus · Accepted Answer

The pH of a solution is defined as the negative logarithm of the hydronium ion concentration, pH=-log[H3O+]. Therefore, to solve for [H3O+] we need to rearrange the equation:

[H3O+] = 10^(-pH)

Substituting the given value of pH = 4.153:

[H3O+] = 10^(-4.153) = 7.03 × 10^(-5) M

Therefore, the concentration of hydronium ions in the solution is 7.03 × 10^(-5) M.

The correct answer choice is D.
