Question

Perovskite is a mineral composed of Ca, Ti and oxygen, cations of titanium lie at the centre, oxides ions at the face centres and calcium ions lie at corners. In this compound the oxidation number of Titanium is + x . Find the value of x?

TestHub · Accepted Answer

Number of C a 2 + ions = 8 × 1 8 = 1 Number of Ti = 1 Number of O - 2 ions = 6 × 1 2 = 3 So the formula of perovskite = C a T i O 3 In C a T i O 3 let oxidation number of Ti = x 2 + x - 6 = 0 x = + 4
