Question

While conducting an experiment on conductivity, two students X and Y passed electricity through sugar solution and inferred that sugar solution is a non-electrolyte. Reasons given by them are
X: Sugar solution has no ions
Y: Sugar solution is not strong enough to conduct electricity.
Correct reason is given by
(a) X only
(b) Y only
(c) Both X and Y
(d) Neither X nor Y

Answer 1

Answer:

C both X and Y your answer

Answer 2

Sugar solution cannot conduct electricity.

Explanation:

Option (a) X only

In the experiment of conduction of electricity, it was found by two students X and Y that sugar solution doe not conduct electricity.

The correct explanation to this statement is: Sugar molecule when dissolved in water does not produces any free ions. This inability of sugar molecule to produce any free ions is a reason of non conductance of electricity.

When electrodes are dipped in aqueous solution of an electrolyte, for example, magnesium chloride, the salt dissociates into its ions that have the mobility to carry charge from one electrode to other. This completes the electrical circuit by flow of electricity.

This phenomenon is not observes in solution of sugar in water.
