What are the metal ions present in carnallite?
- A \(\mathrm{Mg}, \mathrm{K}\)
- B \(\mathrm{Al}, \mathrm{Na}\)
- C \(\mathrm{Na}, \mathrm{Mg}\)
- D \(\mathrm{Zn}, \mathrm{Mg}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Mg}, \mathrm{K}\)
Step-by-step Solution
Detailed explanation
Formula of carnallite is \(\mathrm{KCl} \cdot \mathrm{MgCl}_2 \cdot 6 \mathrm{H}_2 \mathrm{O}\) so, carnallite contains \(\mathrm{K}\) and \(\mathrm{Mg}\).
