By Bronsted definition of acid and base we know
i) A molecule which donates proton (H+) is termed as acid.
ii)A molecule which receives proton is termed as base.
So by that definition in 1st reaction H2SO4 is acid. 2nd reaction NH3 is treated as base . 3rd reaction H2O behaves as base.
5. Kw ionic product of water is defined as Kw = [H3O+] * c [ ] brackets defining concentrations
Kw at room temperature 10-14 and in this case [H3O+] = 10-8
So OH- concentration 10-6 M
