- A \(\mathrm{K}^{+}, \mathrm{Mg}^{2+}\) and \(\mathrm{Cl}^{-}\)
- B \(\mathrm{K}^{+}, \mathrm{Mg}^{2+}\) and \(\mathrm{Br}^{-}\)
- C \(\mathrm{K}^{+}, \mathrm{Zn}^{2+}\) and \(\mathrm{Cl}^{-}\)
- D \(\mathrm{K}^{+}, \mathrm{Ba}^{2+}\) and \(\mathrm{Br}^{-}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{K}^{+}, \mathrm{Mg}^{2+}\) and \(\mathrm{Cl}^{-}\)
Step-by-step Solution
Detailed explanation
(a) Carnallite is a double salt. It will dissociate into simple substances or ions completely when dissolved in water to give 5 ions i.e. \(\mathrm{K}^{+}, \mathrm{Mg}^{2+}\) and \(3 \mathrm{Cl}^{-}\).…
