HCL is added to the solution.

i. state the aim of the experiment.
ii. what was the essence of the addition of sodium hydrogen carbonate?
iii.what would be observed at the end of the experiment.
iv. draw a diagram to illustrate the experiment above.​

Answer 1

The aim of the experiment is to determine what type of reaction occurs. The addition of sodium hydrogen carbonate provides carbon dioxide gas. At the end of the experiment, you would observe a precipitate or color change.

Step-by-step explanation:

The aim of the experiment is to determine what type of reaction occurs. The addition of sodium hydrogen carbonate is to provide a source of carbon dioxide gas, which is needed for certain reactions. At the end of the experiment, you would observe the formation of a precipitate or color change, indicating a chemical reaction has taken place.

Here is a diagram illustrating the experiment:
