O(2-) ions are arranged in ccp in spinel...

`O_(2-)` ions are arranged in ccp in spinel structure. `A^(2+)` ions occupy `1//8` of `TV_(s)` and `B^(o+)` ions occupy half of `OV `. The void volume of unit cell `= 0.11 Å`. Find the value of `A` ?

Text Solution

Verified by Experts

The correct Answer is:
2
(Refer section `1.24.7`)
Void volume `= 0.22//"unit"` volume of unit cell `
`0.11 Å = 0.22 rArr A = 2`

The well known mineral fluorite is chemically calcium fluoride. It is known that in one unit cell of this mineral there are 4 Ca^(2+) ions and 8F^(-) ions and that Ca^(2+) ions are arranged in a fcc-lattice. The F^(-) ions fill all the tetrahedral holes in the face centred cubic lattice of Ca^(2+) ions. The edge of the unit cell is 5.46 xx 10^(-8) cm in length. The density of the solid is 3.18 g cm^(-3) . Use this information to calculate Avogadro's number. (Molar mass of CaF_(2) = 78.08 g mol^(-1) )

The "OLIVINE" series of minerals consists of crystal in which Fe^(2+) and Mg^(2+) ions may substitute for each other causing susbstitutional impurity defects without changing the volume of unit cell. In "OLIVINE" series of minerals, O^(2-) ions exist as fcc with Si^(4+) occupying one-fourth of OVs and divalent metal ions occupying one-fourth of OVs and divalent metal ions occupying one-fourth of TVs . The density of "forsterite" (magnesium silicate) is 3.21 g cm^(-3) land that of "fayalite" (ferrous silicate) is 4.34 g cm^(-3) . If in "forsterite mineral" bivalent Mg^(2+) ions are to be replaced by unipositive Na^(o+) ions, and if Na^(o+) ions are occupying half of TV_(s) in fcc lattice, the arrangement of rest of the constituents is kept same, then the formula of the new solid is:
