Food sources of iron

You can apply the following procedure to test the items written in the list. Note your observations in the table after testing each of the items.

Add 3 to 4 spoons of tea leaves in one litre of water and boil it.

Filter this tea water and store the water in a container.

Take one cup of this tea water from this for the first experiment.

Make a separate solution of the item whose iron content is to be tested, and then filter it using a strainer so that there is no solid part in it. For example, mix 5 grams of jaggery in 10 ml of water and then filter it.

Mix this solution with one cup of tea water.

Keep it aside for 40 to 45 minutes. Is there any change visible in the tea water solution?

After 45 minutes strain this mixture through a filter paper (Whatman number 1)after fitting it in either a funnel or a plastic tea strainer.

It may take 30 minutes or more to strain this mixture. Let the filter paper dry completely once the process is complete.

What did you see on the filter paper?

If there is any black residue on the filter paper, then it indicates the presence of iron.
