Question

Let's repeat this process for the atoms that make up the substances that do not conduct when dissolved in water. What do you notice now?

Answer 1

Substances that do not conduct electricity when dissolved in water, such as pure water and dry table salt, do not contain free-moving ions, which are essential for conductivity. In solid ionic compounds, the crystal lattice structure prevents ion movement. These substances are called insulators, with electrons and ions bound tightly within the structure.

Step-by-step explanation:

When examining the atoms that make up substances that do not conduct electricity when dissolved in water, we notice that these substances do not contain free-moving ions. Substances like pure water, dry table salt, and molecular compounds such as sugar and ethanol are insulators. In insulators, the electrons and ions are tightly bound within the structure, making it extremely difficult for them to move, which is necessary for electrical conductivity.

For an ionic compound like sodium chloride (NaCl), the solid crystal lattice prevents the ions from moving freely. However, when NaCl is dissolved in water, the lattice is disrupted, and the ions are able to move around, which allows for conductivity. This difference in behavior shows why distilled water and solid sodium chloride are non-conductors, while molten salt and salty water are conductors.

In contrast, metals are notable for being good electrical conductors, due to their ability to allow free movement of charge carriers, which are typically electrons.

Answer 2

Step-by-step explanation:

If they do not disolve in water they are non electrolyte and hence will not conduct eletricity. If you had a lab where a batter was supplying power and the wire carryin the electricity went through a water bath if the water was pure and nothing disolved in it the light would not turn on but if you added something like salt it would conduct the electricity
