Which of the following is not an ore of magnesium?
- A Carnallite
- B Dolomite
- C Calamine
- D Sea water
Answer & Solution
Correct Answer
(C) Calamine
Step-by-step Solution
Detailed explanation
Carnallite : \(\mathrm{KCl} \cdot \mathrm{MgCl}_{2} \cdot 6 \mathrm{H}_{2} \mathrm{O}\) Dolomite: \(\mathrm{MgCO}_{3} \cdot \mathrm{CaCO}_{3}\) Calamine : \(\mathrm{ZnCO}_{3}\) Sea water : ore of magneisum \(\therefore\) Calamine is not an ore of magnesium.
