Calculate the pH of a solution that is 0.147M HCl
Mariana [72]

Answer:

pH = 0.832

Explanation:

pH is given by the formula;

pH = - log [H+]

in this case we are given 0.147 M HCl

HCl is a strong acid and therefore completely dissociates to give out H+ ions,

Therefore; [H+] = [HCl] = 0.147 M

Hence;

pH = - log 0.147 M

    <u> = 0.832 </u>
