Q. Which of the following statement is true for degree of dissociation of weak electrolytes?
JIPMER
JIPMER 1996
A
it is inversely proportional to the initial concentration of the electrolyte
B
it is directly proportional to the initial concentration of the electrolyte
C
it is independent of the initial concentration of the electrolyte
D
it depends on the equilibrium concentration of electrolyte
Solution:
According to Ostwalds dilution law, the degree of dissociation of weak electrolytes, $ \alpha =\sqrt{\frac{K}{C}} $ $ \therefore $ $ \alpha \propto \frac{1}{\sqrt{C}} $
