Question

Activity
2.9
Take some approximately 5 g) impure
sample of copper sulphate in a china dish
Dissolve it in minimum amount ofwater
Filter the impurities out.
Evaporate water from the coppersulphate solution so as to get asaturated solution.
Cover the solution with a filter paperand leave it undisturbedat roomtemperature to cool slowly for a day.
You will obtain the crystals of coppersulphate in the china dish.
This process is called crystallisation.

Now answer

What do you observe in the china dish?
Do the crystals look alike?
How will you separate the crystals from
the liquid in the china dish?​

Answer 1

Answer:

the china dish is used to observe the impurities in the produced crystal samples of the given chemical compound.

no crystals are not alike they are like because shape and size of crystals are same and fixed.

You can separate the crystals from the liquid in the china dish by filteration. The water will be separated out and crystals will remain on filter paper.
