If the positions of ` Na^(+) and Cl^(-)` are interchanged in NaCl, having fcc arrangement of ` Cl^(-)` ions then in the unit cell of NaClA. `Na^(+)` ions will decrease by 1 while ` Cl^(-)` ions will increase by 1.B. `Na^(+)` ions will increase by 1 while `Cl^(-)` ions will decrease by 1C. Number of ` Na^(+) and Cl^(-)` ions will remain the sameD. The crystal structure of NaCl will change. |
| Answer» In NaCl with fcc arrangement of `Cl^(-)` ions arrangemetn of ` Cl^(-)` ion = 14, ` Na^(+)` ions = 13. On interchanging their positions, ` Cl^(-)` ions will be 13 and ` Na^(+)` ions will be 14. | |
