What is the hydronium ion concentration of an acid rain sample that has a pH of 3.45? A)2)82 × 10^-11 M B)3)55 × 10^-4 M C)3)45 M D)10.55 M

Question

Quizplus · Accepted Answer

The pH of a solution is defined as the negative logarithm (base 10) of the concentration of hydronium ions (H3O+). Using the pH value given (3.45), we can calculate the hydronium ion concentration:
pH = -log[H3O+]
3.45 = -log[H3O+]
[H3O+] = 10^-pH
[H3O+] = 10^-3.45
[H3O+] = 3.55 x 10^-4 M
Therefore, the hydronium ion concentration of the acid rain sample is 3.55 x 10^-4 M. Choice B is the closest answer to this value.
