Question 1.21: Explain how vacancies are introduced in an ionic solid when a cation of higher valence is added as an impurity in it.
Answer
When a cation of higher valence is added as impurity in an ionic solid . two or more than two cations of lower valances is replace by less than 2 ions of higher valances . To maintain the electrical neutrality few sites become vacant.
For example,
Sr2+ is added to NaCl, each Sr2+ ion replaces two Na+ ions. Because the charge on 1 ions of Sr2+ is equal to charge on two ions of Na+. and One Na+ ions leave there site
