Which of the following will have highest conductivity?
A.)0.1M CH3COOH
B.)0.1 M NaCl
C.)0.1 M KNO3
D.)0.1 M HCl

Dear Student, 

In the given options all electrolyte have the same concentration of 0.1 M, So the conductance or the specific conductance of electrolyte depends upon the dissociation nature of an electrolyte in solution into their respective ions. 
A) CH3COOH will dissociate into 2 ions in solution responsible for the conduction.
B) NaCl will dissociate into 2 ions in solution responsible for the conduction.
C) KNO3 will dissociate into 2 ions in solution responsible for the conduction.
D) HCl will dissociate into 2 ions in solution responsible for the conduction.
And more ions more conduction, But here all have same conductance

So, None of correct option.
