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…

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
