An electrolyte
No.
A substance that dissolves in solution to conduct an electrical current is an "electrolyte" or, less commonly, an "ionogen".
In a normal battery; Copper and Zinc.
Sugar is a compound that dissolves in water but does not conduct electricity. When sugar dissolves in water, it forms a solution, but it does not dissociate into ions that can carry an electric current.
To conduct a solubility test, add a small amount of the substance to a test tube of solvent (such as water) and observe whether it dissolves. If it dissolves, the substance is soluble; if it does not dissolve, the substance is insoluble in that solvent. Repeat the test with different solvents to determine the solubility characteristics of the substance.
Sugar (sucrose) is a material that dissolves in water but does not conduct electric current. Sugar molecules do not ionize in water, so the solution does not carry electric charge.
A substance will conduct an electric current if it forms ions in solution. A solute that produces ions in solution is an Electrolyte. An Electrolytic Solution is a solution that conducts electricity.
When a substance dissolves, clues that indicate its continued presence include the solution's ability to conduct electricity (if the substance is ionic), the presence of specific ions or molecules detectable through chemical tests, and changes in physical properties, such as boiling point elevation or freezing point depression. Additionally, if the solution can be evaporated, the original substance can often be recovered as a solid residue, confirming its existence in a dissolved form.
Sodium chloride, NaCl, for example is of neutral pH and conductive in solution or in molten state. It is a salt.
Ionic substances can conduct electricity because they contain charged particles called ions that are free to move. When an ionic substance dissolves in water or melts, the ions become mobile and are able to carry an electric charge, allowing the substance to conduct electricity.
Because although sugar dissolves in water, it does not produce ions in solution. Electric current travels through solution by hopping from cation to cation and since sugar produces no cations (or ions of any sort) in solution, the current cannot travel through the solution. Therefore, the solution as a whole does not conduct electricity
For a substance or solution to exhibit electrolyte behavior, it must be composed of ions that can move freely in the solution and the substance must be able to conduct electricity when dissolved in a solvent.
