0.1 M HCl is a stong-conductor and 0.1 M HC₂H₃O₂ is a weak-conductor. Explain the difference in conductivity between 0.1 M HCl and 0.1 M HC₂H₃O_2. Relate the difference to the terms strong acid and weak acid.

Expert Solution

HCl is a strong acid whereas CH3COOH (HC2H3O2) is a weak acid.
All strong acids are strong electrolytes which means they completely dissociate to corresponding ions at all dilutions or concentrations. Weak acids are weak electrolytes which means they do not dissociate completely and form a dynamic equilibrium between undissociated molecules and dissociated ions.

We know the conductance of solution depends directly on number of ions in the solution and velocity of the ions. Since strong electrolytes (HCl) produce more ions than weak electrolytes (CH3COOH), Conductance of 0.1M HCl would be superior to 0.1M CH3COOH.

Do let me know if you have any doubts.
