What is the purpose of using a burette in the experiment?

• To measure the volume of acid added

• To heat the solution

• To cool the solution

• To mix the solution

Explain the role of charcoal powder in the reaction.

• To color the solution

• To neutralize the solution

• To filter the solution

• To evaporate the solution

What happens if you add sodium hydroxide before hydrochloric acid in the experiment?

• The solution turns blue

• No reaction occurs

• The solution becomes acidic
