Carnallite in water dissociates to give..... ions.
Options
- AK ⁺, Mg ²⁺ and Cl ⁻
- BK ⁺, Mg ²⁺ and Br ⁻
- CK ⁺, Zn ²⁺ and Cl ⁻
- DK ⁺, Ba ²⁺ and Br ⁻
Correct answer
A. K ⁺, Mg ²⁺ and Cl ⁻
Step-by-step solution
(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. K ⁺, Mg ²⁺ and 3 Cl ⁻ . KCl MgCl ₂ 6 H ₂ O K ⁺+ Mg ²⁺+3 Cl ⁻+6 H ₂ O
