Question

pH of solution is 3.12 calculate the concentration of h3o positive ion​

Answer 1

Explanation:

The 10-6 M H3O+ solution has a pH of 6, and the 10-2 M H3O+ solution has a pH of 2. The solutions are ranked from most acidic (pH = 2) to most basic (pH = 14).pH = - log [H3O+].

The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34?
