Chemistry - Solid State Question with Solution | TestHub

A solid ${\mathrm{A}}^{+}{\mathrm{B}}^{-}$having ZnS-type structure is heated so that all the ions along two of the axis passing through the opposite face centres are lost and bivalent ion ${\mathrm{Z}}^{-2}$ enters the crystal in sufficient numbers to maintain the electrical neutrality of the solid, so that the new formula unit of the final solid becomes ${\mathrm{A}}_{\mathrm{x}}{\mathrm{B}}_{\mathrm{y}}{\mathrm{Z}}_{\mathrm{c}}$.
