Can a sugar solution conduct electric current?

1 Answer

Answer:

Yes but no more than distilled water.

Explanation:

Sugar is a nonconductor.

When it dissolves into water it dissolves as a covalent molecule.

As a covalent molecule it does not conduct electricity in the way that ionic compounds like salt would.

Distilled water contains only #10^"-7"# mol/L of #"H"^"+"# and #10^"-7"# mol/L of #"OH"^"-"#.

This is an exceedingly small amount of ionization.

The water conducts so little current that it is often called a nonconductor.

If tap water is used to make the sugar solution, the ions in the tap water will increase the conductivity about 500-fold.

It is the water in the sugar solution that has the ability to conduct electricity, not the sugar.
