Read the activity carefully.1. Take two flasks, flask A and flask B.2....
Observation of the experiment:
Introduction:
The experiment involves adding washing soda to lemon juice in flask A and adding salt to lemon juice in flask B. The objective is to observe the reaction and determine whether a chemical or physical change takes place.
Bubbles formation:
- In flask A, after adding washing soda to lemon juice, lots of bubbles will be formed. This is because washing soda (sodium carbonate) reacts with the citric acid present in the lemon juice to produce carbon dioxide gas. The release of carbon dioxide gas is responsible for the formation of bubbles.
No bubbles formation:
- In flask B, after adding salt to lemon juice, no significant bubbles will be observed. This is because salt (sodium chloride) does not react with lemon juice to produce any gas. Therefore, there will be no bubbling effect.
Chemical change:
- The formation of bubbles in flask A indicates a chemical change. The reaction between washing soda and citric acid is a chemical reaction that results in the formation of a new substance (carbon dioxide gas).
Physical change:
- The absence of bubbles in flask B indicates a physical change. The addition of salt to lemon juice does not lead to the formation of any new substance or chemical reaction.
Conclusion:
Based on the observations, it can be concluded that the formation of bubbles in flask A indicates a chemical change, while the absence of bubbles in flask B indicates a physical change.
