will the solution of sugar in distilled wafter conduct electticiry
Answers
Answer:
Sugar is such a substance. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity.

Some substances that are made of molecules form solutions that do conduct electricity.
Explanation:
Pure water does not conduct electricity very well. However, when certain substances are dissolved in water, the solution does conduct electricity. You can make a simple device that shows how well a solution conducts electricity. This device uses a flashlight bulb to indicate how well the solution conducts electricity. The better the solution conducts electricity, the brighter the bulb will glow.
Conductivity Tester
To construct the conductivity tester you will need:
● a 12-volt AC adapter
This converts the 110-volt electricity from a wall socket to safer 12-volts. It must be 12 volts AC, not DC, because DC will not work for this. You may have a suitable adapter around the house from an old device you're no longer using, or you may get one from an electronics store (e.g. Radio Shack, catalog number 273-1631).
● an audio cable with a 1/4-inch or 1/8-inch monaural plug on one end
The plug will become the probe for testing conductivity. You may have an unused cable around the house. What is on the other end does not matter because it will be removed. You may also get a suitable plug-and-cable assembly from an electronics supply store (e.g., Radio Shack, catalog number 42-2381).
● a 12-volt flashlight bulb and socket
The bulb will provide a visible indication of how well a material conducts electricity. You can get these from an electronics store (e.g., Radio Shack, catalog numbers 272-1143 for the bulb and 272-357 for the socket).
● a block of wood about 4 by 4 by 1 inch
The electrical connections will be made on this block, and the lamp will be mounted on it, too.
● two 1-inch wood screws
These hold the lamp socket to the block of wood.
● one 3/4-inch round-headed screw and washer
These will be used to make an electrical connection.
● wire cutter and wire stripper
These are used to prepare the electrical connections.
● a screw driver
Cut the plug from the end of the cord of the AC adapter. Separate about four inches of the cord into its two conductors. Remove about 1 inch of insulation from each of the conductors.
Cut the cord of the audio cable about 2 feet from the plug. Remove about four inches of insulation from the cut end of the cable. This will expose bare stranded wire wrapped around insulation that covers a center wire. Unwrap the stranded wires from the insulation and twist the strands together to make a single bundle. Strip about 1 inch of the inner insulation from the center wire.
