WebApr 3, 2024 · There are two ways you can do this. The easy way is to realize that HCl is a strong acid, so its dissociation is considered complete, and [HCl] = [H+]. EASY WAY Recall: pH = −log[H+] From the knowledge that pH = − log[H+] = − log[HCl], we can say: pH = −log(3.1 ×10−3M) = 2.508638306 = 2.51 HARD WAY WebTo determine pH, you can use this pH to H⁺ formula: pH = -log([H⁺]) Step by Step Solution to find pH of 10.2 M : Given that, H+ = 10.2 M Substitute the value into the formula pH = …
