Ionic compounds are good conductors of electricity under specific conditions. Write the two conditions and give reason.

Ionic compounds are good conductors of electricity under the following specific conditions:

When Dissolved in Water (Aqueous Solution):
- Reason: Ionic compounds dissociate into free ions when dissolved in water. These free-moving ions can carry electrical current through the solution.
- Example: Sodium chloride (NaCl) dissolves in water to form Na⁺ and Cl⁻ ions, which can conduct electricity.
When Melted (Molten State):
- Reason: In the molten state, ionic compounds break down into free-moving ions. These ions can move freely and conduct electricity.
- Example: Sodium chloride (NaCl) melts to form Na⁺ and Cl⁻ ions, which can conduct electricity.

Difference Between Good Conductors and Bad Conductors of electricity

Property	Good Conductors	Bad Conductors (Insulators)
Definition	Materials that allow electricity to flow through them easily.	Materials that do not allow electricity to flow through them easily.
Electrical Conductivity	High electrical conductivity.	Low electrical conductivity.
Examples	Metals such as copper, aluminum, and silver.	Non-metals like rubber, glass, and plastic.
Free Charge Carriers	Have free electrons or ions that move easily.	Few or no free electrons or ions available to move.
Heat Conductivity	Also good conductors of heat.	Poor conductors of heat.
Use in Wiring	Commonly used in electrical wiring and components due to their efficiency.	Used as insulators to prevent unwanted flow of electricity and to protect users.
Physical Properties	Usually shiny and metallic.	Typically non-metallic and can be dull or transparent.
Example Reactions	Copper: Cu→Cu2++2e− (in electrolysis)	Rubber: Does not participate in electron transfer.
