Question

Explain why,glucose solution does not conduct electricity whereas common salt solution does ?

Answer 1

glucose is not an electrolyte. when they dissolve in water, they don't dissociate into ions which are necessary for the conduction of electricity. common salt on the contrary is an electrolyte dissolves in water to dissociate into sodium and chlorine and conduct electricity.

Answer 2

When an acid, a base, or a salt is dissolved in water, the molecules break into electrically charged particles called ions. Solutions with ions conduct electricity. Because pure water has few ions, it is a poor conductor. Uncharged molecules that dissolve in water, like sugar, do not conduct electricity.
that's why
glucose solution does not conduct electricity whereas common salt solution does
