The aqueous solution of sugar 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?
- a)Sugar releases more ions in water and increases conductance
- b)Both sugar and NaCl ionises partially in water thereby increasing the conductance
- c)Both sugar and NaCl ionises completely in water thereby increasing the conductance
- d)NaCl ionises completely in water and increase in concentration of salt increases conductance.
Correct answer is option 'D'. Can you explain this answer?

Explanation
The ability of a substance to conduct electricity depends on the presence of free ions in the solution. In the case of sugar, it does not dissociate into ions when dissolved in water. Therefore, an aqueous solution of sugar does not conduct electricity. On the other hand, sodium chloride (NaCl) dissociates into ions when dissolved in water, resulting in the formation of sodium ions (Na+) and chloride ions (Cl-). These free ions are responsible for conducting electricity in the solution.
Dissociation of Sodium Chloride
Sodium chloride (NaCl) is an ionic compound composed of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-). When NaCl is added to water, the polar water molecules surround the Na+ and Cl- ions, causing the ionic bond to break and allowing the ions to move freely in the solution. This process is called ionization or dissociation.
Effect of Concentration
The conductivity of an aqueous solution of sodium chloride depends on the concentration of ions in the solution. As the concentration of sodium chloride increases, more ions are available to carry an electric current, resulting in increased conductivity.
Explanation of Option D
Option D states that NaCl ionizes completely in water, and an increase in the concentration of salt increases the conductance. This statement is correct because NaCl is a strong electrolyte and completely ionizes into Na+ and Cl- ions when dissolved in water. Therefore, a higher concentration of NaCl in the solution means a higher concentration of ions, resulting in increased conductance.
Conclusion
In summary, the ability of a substance to conduct electricity in an aqueous solution depends on the presence of free ions. Sugar does not dissociate into ions in water, while sodium chloride ionizes completely, releasing Na+ and Cl- ions. The concentration of sodium chloride affects the conductance, as a higher concentration means more ions available to carry the electric current. Therefore, option D is the correct explanation of why the addition of sodium chloride to water increases conductivity.

As sodium chloride dissociate in water it will produce Na+ and Cl- ions which will help to conduct electricity
when the concentration is increased more ions will be produced so the conductivity Will also increase
when the concentration is increased more ions will be produced so the conductivity Will also increase
