1.	If the positions of Na^+ and Cl^- are interchanged in NaCl , having fcc arrangement of Cl^- ions then in the unit cell of NaCl
Answer» `NA^+` ions will decrease by 1 while `Cl^-` ions will INCREASE by 1 `Na^+` ions will increase by 1 while `Cl^-` ions will decrease by 1 Number of `Na^+` and `Cl^-` ions will REMAIN the same The crystal STRUCTURE of NaCl wil change Solution :In NaCl with fcc arrangement of `Cl^-` ions , number of `Cl^-` ion =14 , `Na^+` ions =13. On interchanging their positions, `Cl^-` ions will be 13 and `Na^+` ions will be 14
