Which of the following (1 M solution) conducts more electricity?
1 Sulphuric acid
2 Nitric acid
3 Boric acid
4 Phosphoric acid
Explanation:
Strong electrolytes conducts more electricity than weak electrolytes More number of ions furnished by a strong electrolyte more is conductivity.

The reason for increase in electrical conduction of a weak electrolyte with increase in temperature
1 Increase in the number of ions
2 Increase in the speed of ions
3 Increase in the degree of dissociation of electrolytes
4 All the above
Explanation:
Increase in temperature increases the degree of dissociation, so more no. of ions are formed. As the temperature increases, velocities of ions also increase.

The extent of ionisation of weak electrolyte increases
1 With increase in concentration of the solute
2 On addition of excess water
3 On decreasing the temperature
4 On stirring the solution vigorously
Explanation:
Upon dilution, degree of ionization of weak electrolytes increases.

Which of the following statements about solutions of electrolytes is not correct?
1 Conductivity of solution depends upon size of ions.
2 Conductivity depends upon viscosity of solution.
3 Conductivity does not depend upon solvation of ions present in solution.
4 Conductivity of solution increases with temperature.
Explanation:
Solvation capacity is inversely proportional to the conductivity.
