What will happen if sodium chloride is crystallised with a little amount of strontium chloride?
It will create cationic vacancy.
It will create anionic vacancy.
It will crystallize more sodium ions.
It will create metal deficiency.
Each Sr2+ replaces two Na+ ions. Sr2+ occupies the site of one of the Na+ ions and the other site remains vacant.
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.
Improvement in the education system will create more skilled labour.
