Question

Hence, the empirical formu.
3 A crystalline compound is made of elements A, B and
oxygen. The crystal lattice of the compound is based on a
cubic close-packed array of 02- fons with A2+ ions
occupying one-eighth of the tetrahedral voids and B3+
ions occupying half of the octahedral voids. What is the
empirical formula of the compound?​

Answer 1

Answer:

We know that there are two tetrahedral voids and one octahedral void per ion in the given arrangement. <br> Therefore, <br> The no. of octahedral voids per ion in lattice = 1 <br> No. of trivalent cations

<br> The no. of tetrahedral voids per ion in lattice = 2 <br> No. of divalent cations

<br> The formula of mixed oxide is
