Answer 1

Answer #1

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. K_w ionic product of water is defined as K_w = [H₃O⁺] * c [ ] brackets defining concentrations

K_w at room temperature 10^-14 and in this case [H₃O⁺] = 10^-8

So OH^- concentration 10^-6 M
