Understanding Conductors and Electrolytes

What is a key characteristic of a conductor?

• It conducts electricity without chemical change.

• It does not conduct electricity.

• It only conducts electricity in liquid form.

• It changes chemically during conduction.

How do conductors differ from electrolytes in terms of states of matter?

• Electrolytes only work in solid form.

• Conductors work in both solid and liquid states.

• Electrolytes work in solid and liquid states.

• Conductors only work in liquid form.

Which of the following is an example of an electrolyte?

• Copper

• Sodium chloride

• Plastic

• Wood

In what state do electrolytes conduct electricity?

• In any state

• Only in gaseous state

• In molten or aqueous solutions

• Only in solid state

Which of the following is NOT an electrolyte?

• Plastic

• Salt

• Alkali

• Acid

What is a non-electrolyte?

• A liquid that always conducts electricity.

• A solid that conducts electricity.

• A liquid that does not allow electricity to pass through.

• A substance that conducts electricity in solid form.

What is the main difference between strong and weak electrolytes?

• Weak electrolytes conduct electricity better.

• Strong electrolytes do not conduct electricity.

• Weak electrolytes are always solid.

• Strong electrolytes completely dissociate in solution.

What happens to sodium chloride when it is dissolved in water?

• It becomes a non-electrolyte.

• The ions remain fixed.

• It forms a solid.

• The ions become free to move.

What is the role of ions in conducting electricity in electrolytes?

• Ions carry charge and move freely.

• Ions prevent electricity flow.

• Ions convert to non-ionic compounds.

• Ions are fixed and do not move.

Why can't solid sodium chloride conduct electricity?

• It is a non-ionic compound.

• It has no ions.

• The ions are fixed in place.

• The ions are free to move.
