Why is one electrolyte able come conduct electrical energy while a Nonelectrolyte Cannot?
Electrolytes and Non-electrolytesChemical substances can be classified into electrolytes and non-electrolytes.
You are watching: A substance that does not conduct electricity as a solid
Electrolytes space substances that can conduct power either in the molten state or in an aqueous solution and undergo chemical changes.Non-electrolytes room substances that cannot conduct electricity either in the molten state or in one aqueous solution.Conductors space substances that deserve to conduct electricity in the solid or molten state yet are no chemically changed. Therefore, conductors space not electrolytes.Figure illustrates the corpuscle in an electrolyte and a non-electrolyte.

Electrolytes and also Non-electrolytes Experiment
Aim: to classify substances into electrolytes and also non-electrolytes.Materials: heavy lead(II) bromide, acetamide, naphthalene, sodium hydroxide solution, glucose solution and also copper(II) sulphate solution.Apparatus: Batteries, bulb, switch, connecting wires v crocodile clips, carbon electrodes v holders, crucible,100 cm3 beaker, Bunsen burner, tripod stand and pipe-clay triangle.Procedure:
A. Because that molten substancesTwo-thirds of a crucible is filled through solid lead(II) bromide, PbBr2.The apparatus is set up as displayed in Figure.
B. Because that aqueous solutionsA maker is filled through sodium hydroxide, NaOH equipment until that is half full.The apparatus is set up as displayed in Figure.
|Molten lead(ll) bromide||The pear lights up. A brown gas is exit at one of the electrodes.|
|Molten acetamide||The bulb does no light up. No adjust at the electrodes|
|Molten naphthalene||The bulb does not light up. No readjust at the electrodes.|
|Sodium hydroxide solution||The bulb lights up. Effervescence occurs at both electrodes.|
|Glucose solution||The pear does no light up. No adjust at the electrodes.|
|Copper(ll) sulphate solution||The bulb lights up. Effervescence occurs at one of the electrodes vice versa, a brown solid is deposited on the other electrode.|
Discussion:Molten lead(II) bromide, sodium hydroxide solution and also copper(II) sulphate solution deserve to conduct electricity. This is since they contain totally free mobile ion which can lug electric current.

Conclusion:Molten lead(II) bromide, salt hydroxide solution and also copper(II) sulphate solution space electrolytes conversely, molten acetamide, molten naphthalene and also glucose solution space non-electrolytes.
