Among the following, which solution is the most acidic? Question 17 options: [OH-] = 1 * 10-7 mol/L pH = 10 [H+] = 1 * 10-5 mol/L pH = 3

Answer;

[H+] = 1 * 10-5 mol/L pH = 3

Explanation; This can be explained by the fact that; In an acidic solution, [H+] > [OH-]., that is the concentration of hydrogen ions is higher than that of hydroxyl ions. On the other hand, in a basic solution, [OH-] > [H+], while in a neutral solution, both concentrations are equal, that is; [H+] = [OH-] The pH of a solution is equal to the base 10 logarithm of the H + concentration, multiplied by - 1. pH is used to measure how acidic or basic a substance is. The more the pH the more basic it is an the lower the pH the more acidic it is.
