Question

Glucose dissolves in water but doesn't produce ions during dissolution process. Two (positive and negative) electrodes that were hooked up to a light bulb and external source of power were placed in an aqueous solution of glucose. What was observed during experiment?

Answer 1

Electricity does not pass in non-electrolyte solution so bulb can not light.

Step-by-step explanation:

Glucose is an organic compound that is made up of carbon, hydrogen, oxygen atoms. It is a type of polar molecule because it contains a hydroxyl group. Since the carbon-carbon bond and some other bond that are present in this compound is a covalent bond. When glucose is dissolved in water it does not dissociate into ions. So during the experiment bulb can not light due to the absence of ions. Such types of substances that do not dissociate into ions are knowns as nonelectrolytes such as glucose and some other substances.
