What happens when AgCl is doped with 2? CdCl What is the name of this defect?
Sum
Solution
When AgCl is doped with CdCl2
In this case two Ag- ions are replaced by one Cd+2 ions.
The 2 Cd2+ ion occupies the site of one of the Ag- ion and a cation vacancy is created at the site of the other Ag- ion.
The cationic vacancies thus produced are equal in number to that of Cd2+ ions. This is impurity defect.
