Question 8

How will you test that ‘tea dust’ is not adulterated with iron powder?

Answer 1

To test whether tea dust is adultered with iron powder, we can do a simple experiment.

(i) Take tea sample and spread it on a paper.

(ii) Take a bar magnet in your hand and move it over the tea dust.

(iii) If some particles are attracted strongly towards the magnet by clinging to it, then the tea dust is adultered with iron powder.
