Question

The constituents of a mixture of CaCO, and NaCl is separated by:
(a) Using the evaporation method
(b) Using the sublimation method
(c) Dissolving in water, filtration and evaporation
(d) Using the distillation method​

Answer 1

Answer:

CaCO3 is poorly soluble in water while NaCl will dissolve completely in the water. Then, separate the insoluble CaCO3 from the NaCl solution by filtration. Obtain the CaCO3 as the residue and the NaCl solution as the filtrate. Carry out crystallisation using the NaCl solution to collect solid NaCl crystals.

Answer 2

Answer:

option (c)-Dissolving in water, filtration and evaporation
