Perovskite is a mineral composed of Ca, ...

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?

A

`+2`

B

`+3`

C

`+4`

D

`+3//4`

Text Solution

Verified by Experts

The correct Answer is:
C
No. of calcium atoms =`8times1/8=1`
No. of oxygen atoms=`6times1/2=3`
No. of titanium atoms=`1times1=1`
`therefore"Formula of the mineral "CaTiO_(3)`
Let `O.N." of "Ti=x`
`therefore 2times1+x+3(-2)=0`
2+x-6=0
x=4
