Question

to show break down of food by using the model of chalkpiece kept in vinegar

Answer 1

NOTE:Chalk is calcium carbonate while both vinegar and lemon juice are acidly. The vinegar or lemon juice acidity dissolves the chalk.and so the experiment happens.

EXPERIMENT::-

PROCEDURE:

Set one piece of chalk aside on the table.

Using either lemon juice or vinegar, fill a glass half full with the liquid.

Place the chalk in the glass. 

The chalk does not have to be completely covered in the liquid.Set the glass aside for a couple of days.

The chalk should begin dissolving and then be completely dissolved in a few days.

You can try this chalk science experiment in school or at home using both vinegar and lemon juice.Put a piece of chalk (or half of a piece) into a glass of vinegar.

Put the other half of the chalk (or a full piece) in a glass of lemon juice.The chalk will dissolve same as the food dissolve in our digestive system(gastric acid)
