Question:
Calamine, malachite, magnetite and cryolite, respectively, are:
ZnSO4,Cu(OH)2,Fe3O4,Na3AlF
ZnCO3,CuCO3,Fe2O3,Na3AlF
ZnSO4,CuCO3,Fe2O3,AlF
ZnCO3,CuCO3.Cu(OH)2,Fe3O4,Na3Al
Solution:
Correct option is D.ZnCO3,CuCO3.Cu(OH)2,Fe3O4,Na3Al
Calamite is an ore of zinc, malachite is an ore of copper, magnetite is an ore of iron and cryolite is an ore of aluminium
(i) Calamine,ZnCO3
(ii) Malachite,CuCO3.Cu(OH)2
(iii) Magnetite,Fe3O4
(iv) Cryolite,Na3AlF6.
Hence the correct answer is option (D).
