Question

an acid ha is 40% disassociated in aqueous solution the hydronium ion concentration of its 0.2 m is​

Answer 1

Explanation:

Acid -base reaction is as follows:

HA+H

2

O→H

3

O

+

+A

−

Given, degree of dissociation (α)=40%=0.4

For weak acid, hydronium ion concentration is

[H

3

O

+

]=Cα=0.2×0.4=0.08
