Properties and Characteristics of Electrolytes

The video explores whether sodium nitrate (NaNO3) is an electrolyte. It defines electrolytes as substances that dissolve in water to produce ions, enabling electrical conductivity. Sodium nitrate, an ionic compound, is highly soluble in water, dissociating into sodium and nitrate ions. This dissociation confirms that sodium nitrate is a strong electrolyte, as it conducts electricity when dissolved in water.

What is the primary characteristic of an electrolyte?

• It dissolves in non-polar solvents.

• It produces ions in solution.

• It does not conduct electricity.

• It remains solid in water.

What type of compound is sodium nitrate (NaNO3)?

• Non-metallic compound

• Metallic compound

• Ionic compound

• Covalent compound

Which element in sodium nitrate is a metal?

• Sodium

• Oxygen

• Nitrogen

• Nitrate

Why is sodium nitrate considered very soluble?

• Because it is a gas at room temperature.

• Because it forms covalent bonds.

• Because it breaks apart into ions in water.

• Because it is a non-polar compound.

What charge does the sodium ion (Na) carry?

• One plus

• Two plus

• Two minus

• One minus

What is the charge on the nitrate ion (NO3)?

• One plus

• Two plus

• One minus

What does the term 'aqueous' (aq) indicate about a compound?

• It is dissolved in water.

• It is a solid.

• It is insoluble.

• It is a gas.

Why is sodium nitrate classified as a strong electrolyte?

• It forms a precipitate.

• It completely dissociates into ions in water.

• It does not dissolve in water.
