Chemical Reaction of Sodium and Chlorine

In this video tutorial, a small piece of sodium metal is placed in a flask containing yellow chlorine gas. Sand is added to the flask to prevent the heat generated by the reaction from cracking the glass. Initially, no reaction occurs between the sodium and chlorine. The reaction is initiated by adding a drop of water to the sodium, which triggers the chemical process.

What is placed in the flask along with sodium metal?

• Water

• Yellow chlorine gas

• Hydrogen

• Oxygen

Why is sand added to the flask?

• To change the color of the gas

• To react with sodium

• To prevent the flask from breaking due to heat

• To absorb moisture

What is the initial observation when sodium is placed in the flask with chlorine?

• Immediate reaction

• No reaction

• Explosion

• Color change

How is the reaction between sodium and chlorine initiated?

• By shaking the flask

• By adding more chlorine

• By adding a drop of water

• By heating the flask

What is the role of water in the reaction?

• To cool down the reaction

• To dissolve sodium

• To initiate the reaction

• To change the color of chlorine
