Vedclass · Answer

(B) When $CaCl_2$ is added to $AgCl$ crystal,each $Ca^{2+}$ ion replaces two $Ag^{+}$ ions to maintain electrical neutrality. Since one $Ca^{2+}$ ion replaces two $Ag^{+}$ ions,one $Ag^{+}$ site remains vacant,creating a cation vacancy. This type of defect is a form of impurity defect,which is related to the Schottky defect mechanism where vacancies are created in the lattice. Therefore,the introduction of $CaCl_2$ into $AgCl$ leads to the formation of cation vacancies,which is characteristic of Schottky-type defects. Thus,the correct option is $B$.
