Answer:
define degree of dissociation. derive Ostwald's dilution law for the COOH
Answer:
Ostwald’s dilution law describes the dissociation constant of the weak electrolyte with the degree of dissociation (α) and the concentration of the weak electrolyte.
A binary electrolyte AB which dissociates into A+ and B– ions.
AB ⇌ A+ + B–
(i) For very weak electrolytes, since α <<< 1, (1 – α) = 1
∴ K=Cα2
α=KC−−√
(ii) Concentration of any ion = Cα = √CK = √K/V
K =dissociation constant of a weak acid
α = degree of dissociation.
Ostwald’s dilution law states that only at infinite dilution the weak electrolyte undergoes complete ionization.
