HCl is HYDROCHLORIC ACID and results a VERY STRONG ACID because It takes part to ionic dissociation in aqueous solutions TO GIVE HYDRONIUM IONs (e.g. H3O+)
HCl(aq) + H2O(aq) ---> H3O+(aq) + Cl-(aq)
Now, We may assume that
|HCl| = |H3O+| = 2 M
Here, We need to assume that all the acid will dissociate into its ionic state!
So, Concentration of H+ ions = 2.0 M
pH=−log[H+]
Log (2) = 0.301
pH = - log = - 0.301 (VERY highly acidic)
