The degree of dissociation of ammonium hydroxide is 0.0232 in 0.5 M so

1.	The degree of dissociation of ammonium hydroxide is 0.0232 in 0.5 M solution. What will be the dissociation constant of ammonium hydroxide?
Answer» Given : Degree of dissociation = α = 0.0232 Concentration of NH₄OH = C = 0.5 M Dissociation constant = K_b = ? K_b = Cα² = 0.5 × (0.0232)² = 2.692 × 10^-4 ∴ Dissociation constant of NH₄OH = K_b = 2.692 × 10^-4

The degree of dissociation of ammonium hydroxide is 0.0232 in 0.5 M solution. What will be the dissociation constant of ammonium hydroxide?

Answer»

Given :

Degree of dissociation = α = 0.0232

Concentration of NH₄OH = C = 0.5 M

Dissociation constant = K_b = ?

K_b = Cα²

= 0.5 × (0.0232)²

= 2.692 × 10^-4

∴ Dissociation constant of NH₄OH = K_b = 2.692 × 10^-4
