Question

Crystals of copper sulphate are obtained from its solution by the process of
a) sublimation b) crystallization c) boiling d) evaporation​

Answer 1

Answer:

answer is b option

Explanation:

Pure copper sulphate can be obtained from an impure sample by re-crystallization. The impure sample is dissolved in water, heated and then cooled which then later forms crystals. These copper sulphate crystals are then separated by filtration and drying

Answer 2

$\huge{\sf{\red{\underline{Required~Answer}}}}$

Crystals of copper sulphate are obtained from its solution by the process of crystallization.

______________________________

Crystallization -

• It is a process by which crystals of a substance are obtained by cooling a hot saturated solution.

Crystal -

• It is a homogeneous solid of definite geometrical shape. It has symmetrically arranged smooth plane which meet forming the sharp edges.

Copper sulphate -

• Its chemical formula is $\sf{CuSO_4 • 5 {H_2}O}$

Test for copper sulphate -

• Add a few drops of water, if the white powder turns blue its copper sulphate.
