In a solid, B ⁻ ions occupy corners of a cube forming ccp structure. If A⁺ ion occupy half the tetrahedral voids, formula of the solid is

Step-by-step solution

B ⁻ ions occupy corners of cube and forms ccp structure. The number of tetrahedral voids generated is twice the number of B ⁻ ions. Thus, number of tetrahedral voids =2 ~B A ⁺ ions occupy ( 1 / 2 ) of these tetrahedral voids. Hence, number of A ⁺ ions =2 ~B 1 / 2=1 ~B Ratio of A ⁺ and B ⁻ ions =1 ~B : 1 ~B =1: 1 Formula of compound = AB
