Question

Rehan put salt and chalk in a glass of water .how can he separate them​

Answer 1

Answer:

We can separate the mixture of common salt and chalk powder by putting the mixture in water. As we know that common salt is a homogeneous mixture, so it will dissolve with water uniformly and chalk powder is heterogeneous so it could be separated by the filtration method by using filter paper.

Answer 2

Answer:

DISSOLVE THE MIXTURE OF SAND AND CHALK POWDER IN WATER AND FILTER THE SOLUTION . THE SAND IS COLLECTED AS A RESIDUE IN THE FILTER PAPER. EVAPORATE THE FILTRATE SO AS TO OBTAIN CHALK POWDER
