Describe kohlrausch s law. give its two applications
Answers
Answer:
the migration of an ion at infinite dilution is dependent on the nature of solvent and on the potential gradient but not on others ions present.
1. determination of limiting molar conductivities for any electrolyte.
Weak electrolyte s have lower molar conductivities and lower degree of dissociation at higher concentration.
Answer:
It states that the molar conductivity of a weak electrolyte at infinite dilution equal to molar conductivity at infinite dilution of cation + anion.
Explanation:
APPLICATION: •used to calculate degree of dissociation ( alpha) where
alpha[α]= molar conductivity
. .......................................
molar conductivity at infinite
dilution
• used to calculate dissociation constant (Kc)
Kc= c{α}^2. where c= concentration
...............
1-α
