Why on dilution the ˄m of CH3COOH increases

Question:
Why on dilution the ˄m of CH3COOH increases drastically, while that of CH3COONa increases gradually?

Solution:

CH3COOH is a weak electrolyte and CH3COONa is a strong electrolyte. A weak electrolyte has a lower degree of dissociation at higher concentration but upon dilution, the degree of dissociation increases, the number of ions per unit volume increases and this lead to an increase in.
