The PH of a solution of Hcl is 2.what is the amount of acid present in a litre of the solution ​

Explanation:

By DEFINITION… pH , i.e. pouvoir hydrogène , “power of hydrogen” , pH=−log10[H3O+] .

And so if pH=2 , we take REVERSE logarithms..i.e. [H3O+]=10−2∙mol∙L−1 … [H3O+]=0.010∙mol∙L−1 …,

We know that hydrochloric acid, for which the protolysis is complete, undergoes the reaction..

HCl(aq)+H2O(l)→H3O++Cl−

The solution is thus stoichiometric in hydronium ion…

have a great day because if you dont you and i will be sad
