Classify A & B correctly in the following chart:
A - Strong Electrolyte
B - Strong Electrolyte
A - Weak Electrolyte
B - Weak Electrolyte
A - Strong Electrolyte
B - Weak Electrolyte
A - Weak Electrolyte
B - Strong Electrolyte
The conductance of a solution increases with an increase in the number of solute molecules/ions and decreases with a decrease in the number of solute molecules/ions.
Strong electrolytes: There is almost no change in the degree of dissociation (as it is already close to unity).
Weak electrolytes: With dilution, the degree of dissociation increases rapidly, and thus, the number of molecules increases.
In weak electrolytes molecules increases rapidly and graph B is showing this.
A is strong electrolyte like NaCl and B is weak like CH3COOH
Therefore, option(3) is correct
