Which of the following statements is/are false: a. A solution of sulphuric acid or hydrochloric acid in water conducts electricity. b. The materials that do not allow electric current to pass through them are called poor conductors of electricity. c. A solution of copper sulphate or sodium chloride in water will not conduct electricity.

Statement ‘c’ is a false statement. Thus, it is the correct option. A compound that allows electric current to pass through itself, when either in a molten state or in an aqueous solution, is called an electrolyte. Solutions of sodium chloride, copper sulphate, dilute sulphuric acid are examples of strong electrolytes. Statement ‘b’ is a correct statement. But, statement ‘c’ is a false statement. Thus, it is a wrong option. A solution of copper sulphate or sodium chloride in water will conduct electricity because they are basic in nature.
