As a subject matter expert in the field of chemistry with a focus on solutions and their properties, I can provide a detailed explanation regarding the conductivity of sugar in water.

When sugar, which is sucrose, is dissolved in water, it forms a solution. Sucrose is a nonelectrolyte, meaning it does not dissociate into ions when dissolved in water. Conductivity in solutions is primarily due to the presence of free-moving ions. Since sucrose does not produce ions in solution, a sugar solution is not typically considered to be conductive.

However, it's important to note that water itself can have some conductivity due to the self-ionization of water molecules, which produces a very small number of hydrogen ions (H+) and hydroxide ions (OH-). This is a natural process and contributes to water's slight conductivity, but the level is very low compared to solutions with strong electrolytes.

In summary, while a sugar solution in water is not a good conductor due to the lack of free-moving ions from the sugar itself, the water can still have a slight conductivity due to its own self-ionization.

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. ... When ammonia dissolves in water, it reacts with the water and forms a few ions.read more >>
