¿Qué es la Electrólisis? - Reacciones

The video tutorial explains how electrical current can flow through certain liquids, specifically those that are ionic compounds, molten, or aqueous solutions. It uses sodium chloride as an example, detailing how it melts at temperatures above 801°C, allowing sodium and chloride ions to move freely and conduct electricity.

What is necessary for a liquid to conduct electricity?

• It must be a non-ionic compound.

• It must be an ionic compound, either molten or aqueous.

• It must be a solid compound.

• It must be a gaseous compound.

At what temperature does sodium chloride need to be heated to become conductive?

• 801°C

• 500°C

• 600°C

• 1000°C

What happens to sodium chloride when it is heated above 801°C?

• It becomes a gas.

• It melts and forms a liquid with free-flowing ions.

• It remains solid.

• It decomposes into sodium and chlorine gas.

Which ions are present in molten sodium chloride?

• No ions

• Only chloride ions

• Only sodium ions

• Both sodium and chloride ions

What is the significance of free movement of ions in liquid sodium chloride?

• It allows the liquid to conduct electricity.

• It makes the liquid solidify.

• It prevents the liquid from conducting electricity.

• It causes the liquid to evaporate.
