Question

The aqueous solution of sugart does not conduct electricity. However when sodium chloride is added to water, it conducts electricity. How will you explain this statement on the basis of ionisation and how is it affected by concentration of sodium chloride ?

Answer 1

Sugar `(C_(12)H_(22)O_(11))`is a covalent solid and does not dissociate into ions in aqueous solution. Sodium chloride (NaCI) is an ionic solid and dissociates into ions in aqueous solution. Therefore it is conducting in aqueous solution. The electrical conductivity of sodium chloride or any other salt in water increases as more of ions more of ions are formed in solution.
