The dissociation constant of acetric aci...

The dissociation constant of acetric acid and hydrogen cyanide are `1.8 xx 10^(-5)` and `3.2 xx 10^(-10)` respectively. If the degree of hydrolysis of potassium cyanide and potassium acetate are `h_(1)` and `h_(2)` respectively then:

Text Solution

Verified by Experts

Dissociation of hydride is given as,
`H_(2)MhArrH^(+)+MH^(-)`
  For this dissociation equilibrium, a lower value of `K_(a)` denotes that the acid is weak.
As the `K_(a)` values increase from `H_(2)O` to `H_(2)Te`, their acidic strength also increases. `H_(2)Te` is retalively a stronger acid.
