Question

A solid solution of $CdB{r}_2$ in $AgBr$ contains:

• A. schottky defects
• B. frenkel defects
• C. colour centres
• D. frenkel as well as schottky defects

Answer 1

Answer: (D)

frenkel as well as schottky defects

Stoichiometric Defect - These are point defects that do not disturb' the stoichiometric of the solid. They are also called intrinsic or thermodynamic defects . In ionic solids, basically these are of two types , Frankel defects and Schottky defect.
