Answer #1

Concepts and reason

The strength of acid is related to its dissociation constant or ionization constant in aqueous solution. It is equilibrium constant of dissociation reaction of an acid.

Fundamentals

The quantitative measure of strength of acid can be measured by acid dissociation constant, Ka or acid ionization constant.

Arrhenius’s theory defines acid as a substance that dissociates in aqueous solution and releases the hydrogen ion or proton.

HA
A
+H

The dissociation of is given below:

HCN
Hai +CN (aa)

The reaction for dissociation of HCN in water is given below:

HCN0g) +H,0
H,0* + CN ()
K - [H,0* ][CN]
[HCN]

Ans:

The Ka for reaction of HCN is given below:

HCN- +H,0
H2O*v +CN()

The Kb value is given below:

K = 1.6x10-5
