(d) Sand, sugar and iron-filings
Answers
Hey mate here is your answer!!
Answer:
a. sand and iron filings with magnet and camphor using sublimation.
b. sand through sedimentation and secantation and dal and husk through winnowing.
c. Iron filings can be separated with the help of magnet and salt can be separated through evapouration.
d. iron filings with magnet and sugar through evapouration.
hope this helps you!!
(a) Iron powder is separated by using magnet. Camphor powder is separated by sublimation. Water is added to the remaining mixture. Sand being insoluble in water, it can be separated by filtration.
(b) Sand and husk can be separated by the method of winnowing.
(c) The iron nails and sand mixture can be easily separated using magnetic separation methods. But in a salt solution, salt and water cannot be separated so easily. The separation techniques like condensation and evaporation are used to extract water and salt separately.
(d) Iron is magnetic and the other two not, which means a magnet could be used to attract the iron filings out of the mixture, leaving the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
