If NaCl is doped with 10−3mol % of SrCl2′, each Sr2+ ion replaces – InterviewSolution

1.	If NaCl is doped with 10−3mol % of SrCl2′, each Sr2+ ion replaces two Na+ ions, but occupies only one lattice point in place of Na+ ion. This creates one cation vacancy.
Answer» If NaCl is doped with $10^{- 3} m o l %$ of $S r C l_{2^{'}},$ each $S r^{2 +}$ ion replaces two $N a^{+}$ ions, but occupies only one lattice point in place of $N a^{+}$ ion. This creates one cation vacancy.
