How is the percentage concentration calculated for sulfuric acid with PH=1? Is it as follows: =10^(-PH) = 0.1 mol/l, =1/2* = 0.05 mol/l; C(h2so4) = 0.05*98/1000 = 0.49%? Is that correct? The above is an algorithm I saw on the internet. But there is another formula as follows: C(h2so4) = *M/1000/P, where M is the amount of substance of sulfuric acid taken as 98, and P is the density of sulfuric acid at pH 1. That method is correct; thank you very much!
