What is the hydrogen ion concentration in a solution with pH = 2.34? A)4.57 × 10^-3 M B)2.34 × 10^-3 M C)2.19 × 10^-12 M D)1.17 × 10¹ M E)4.27 × 10^-12 M

Question

Quizplus · Accepted Answer

The hydrogen ion concentration can be calculated using the equation pH = -log[H+]. Rearranging this equation gives [H+] = 10^(-pH). Substituting pH = 2.34 gives [H+] = 10^(-2.34) = 4.57 × 10^-3 M, which is answer choice A.
