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 _{.So, the increase in drastic}

_{For strong electrolytes upon dilution, the number of ions doesn’t change,but interionic attraction decreases and hence the increase is gradual.}
