Chemistry - Solid State Question with Solution | TestHub

The mineral perovskite has a structure that is the prototype of many$\mathrm{A}\mathrm{B}{\mathrm{X}}_3$solids particularly oxides. The perovskite structure is cubic with A atoms surrounded by 12 X atoms and the B atoms surrounded by 6 X atoms. The sum of charges on the cations A and B must be +6; it can be achieved in several ways$({\mathrm{A}}^{2+}{\mathrm{B}}^{4+}$and${\mathrm{A}}^{3+}{\mathrm{B}}^{3+}$among them). Oxidation state of titanium in$\mathrm{C}\mathrm{a}\mathrm{T}\mathrm{i}{\mathrm{O}}_3$(Perovskite) is
