Question

K in K = Cα^2/1 – ɑ represents ___________

(a) dissociation constant

(b) molar concentration

(c) degree of dissociation degree of ionization

(d) degree of ionization

The question was posed to me in an online interview.

My query is from Ionic Equilibrium in Solution topic in section Equilibrium of Chemistry – Class 11

Answer 1

Right choice is (a) dissociation constant

For explanation: The above equation represents Ostwald’s dilution law, where K is the dissociation constant, C is the molar concentration of the solution and ɑ is a degree of dissociation or degree of ionization of the solution.
