The chemical name for table sugar is sucrose (C12H22O11). To classify this compound first we have to know what happens when this compound is in the solution. If it is an acid, it will release hydrogen ions (H+) in the solution. Conversely, it is a base if it will release hydroxide ions (OH-) in the solution. If it is a salt, it should form ions in the solution.
When dissolved in water, sugar does not produce H+ or OH-. So we can say that Sugar is not classified among the three options. This can be classified as a neutral compound or non-electrolyte.
easier answer : its neutral
