A mineral of titanium (perovskite) is found to contain calcium ions at the corners, oxygen atoms at the face centres and titanium atoms at the centre of the cube. The oxidation state of titanium in the mineral is

A

`+2`

B

`+3`

C

`+4`

D

`+1`

Text Solution

Verified by Experts

The correct Answer is:
C
Ca atoms per unit cell =` 8xx 1/8 =1 `
O atoms per unit cell =` 6 xx 1/2 =3`
Ti atom per unit cell =1
Hence, the formula of the mineral is ` CaTiO_(3)`
Suppose ox. No. of Ti =x .
Then + 2 + x + 3 (-2) = - or x = +4
