Options
- A(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- B(A)-(I), (B)-(III), (C)-(II), (D)-(IV)
- C(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
- D(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
Correct answer
A. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Step-by-step solution
Double salts dissociate completely into simple ions in aqueous solution, whereas complex salts retain their complex ion. (A) Carnallite is a double salt with the formula KCl MgCl ₂ 6 H ₂ O . It dissociates into 1 K ^+ , 1 Mg ²⁺ , and 3 Cl ^- , yielding a total of 5 ions. So, (A) matches with (III). (B) Potash Alum is a double salt with the formula K ₂ SO ₄ Al ₂( SO ₄)₃ 24 H ₂ O . It dissociates into 2 K ^+ , 2 Al ³⁺ , and 4 SO ₄²⁻ , yielding a total of 8 ions. So, (B) matches with (I). (C) K ₃[ Fe ( CN )₆] is a com
