What type of crystal defect is produced when sodium chloride is doped with ` MgCl_(2)` ?

Explanation

To determine the type of crystal defect produced when sodium chloride (NaCl) is doped with magnesium chloride (MgCl2), we can follow these steps:

### Step 1: Understand the Composition of NaCl and MgCl2
- Sodium chloride (NaCl) is composed of sodium ions (Na⁺) and chloride ions (Cl⁻).
- Magnesium chloride (MgCl2) consists of magnesium ions (Mg²⁺) and chloride ions (Cl⁻).

### Step 2: Analyze the Doping Process
- When MgCl2 is introduced into the NaCl crystal lattice, the magnesium ions (Mg²⁺) can substitute for sodium ions (Na⁺) because they are both cations, but Mg²⁺ has a +2 charge compared to the +1 charge of Na⁺.
