Question

38. Dissociation of water can be expressed as
(1) K = (H*](OH"]/[H20)
(2) K =(H+ (OH]/[OH-]
(3) K =[HⓇ][120]/[H,01
(4) K = [HỎ JOH] [H]​

Answer 1

Explanation:

H

+

+OH

−

⟶H

2

O;ΔH=−13.7×4.18kJ=−57.27 kJ

Heat of dissociation of H

2

O into H

+

and OH

−

will be positive.

Hope it helps ☺️
