Ionic Compounds and Electrical Conductivity

The video tutorial explains the electrical conductivity of ionic compounds using NaCl as an example. It highlights that for conductivity, charged particles must be present and free to move. In solid state, ions are immobile, preventing conductivity. However, in molten and aqueous states, ions can move freely, allowing electricity to flow.

What are the two essential conditions for electrical conductivity in ionic compounds?

• Presence of charged particles and their ability to move freely

• Presence of neutral particles and their ability to move freely

• Presence of neutral particles and their fixed position

• Presence of charged particles and their fixed position

Why can't ionic compounds conduct electricity in their solid state?

• Because the ions are fixed in place and cannot move

• Because the ions are too far apart

• Because there are no charged particles

• Because the ions are free to move

What happens to the ions in an ionic compound when it is in a molten state?

• The ions remain fixed in place

• The ions become neutral

• The ions are free to move

• The ions disappear

In the molten state, which direction do chloride ions move when a battery is applied?

• Towards the positive plate

• Towards the negative plate

• They move randomly

• They do not move

How do ionic compounds behave when dissolved in water?

• The ions are free to move

• The ions disappear

• The ions remain fixed in place

• The ions become neutral

What role do hydrogen ions play in the movement of chloride ions in water?

• They have no effect on chloride ions

• They neutralize chloride ions

• They attract chloride ions

• They repel chloride ions

Why can ionic compounds conduct electricity in an aqueous solution?

• Because the ions are free to move

• Because the ions are neutral

• Because the ions are fixed in place

• Because there are no charged particles

What is the main reason ionic compounds cannot conduct electricity in solid form?

• Lack of charged particles

• Ions are not free to move

• Ions are neutral

• Ions are too far apart

In which states can ionic compounds conduct electricity?

• Solid and molten

• Solid and aqueous

• None of the above

• Molten and aqueous

What is the key factor that allows ionic compounds to conduct electricity?

• Absence of charged particles

• Fixed position of ions

• Mobility of ions

• Presence of neutral particles
