Question

Define degree of dissociation.

Answer 1

Degree of dissocsavIt is defined as a fraction of total number of moles of an electrolyte that dissociate into its ions at equilibrium.

It is denoted by a and represented by,

α = \(\frac{number\,of\,moles\,dissociated}{total\,number\,of\,moles\,an\,electrolyte}\)

OR,

α = \(\frac{Percent\,dissociation}{100}\)

∴ Percent dissociation = α × 100
