Solid State & Surface Chemistry - Question 5

A binary solid (A+ B-) has a zinc blends structure with B- ions constiuting the lattice and A+ ions occupying 25% tetrahedral holes. The formula of solids is:

Detailed Solution for Solid State & Surface Chemistry - Question 5

No. of B- ions in unit cell 

Now A+ ions occupies 25% of tetrahedral holes 

Thus, ratio of B- to  AA+ is 2 : 1 or formula is AB2

Solid State & Surface Chemistry - Question 6

Which of the following statement is not correct?    

Detailed Solution for Solid State & Surface Chemistry - Question 6

Solid State & Surface Chemistry - Question 7

If NaCI is doped with 10-4 mole % of SrCI2, the concentration of cation vacancies will be :

Detailed Solution for Solid State & Surface Chemistry - Question 7

Dropping of SrCI2 to NaCI brings in replacement of two Na+ by each Sr2+ ion, but Sr2+ occupies one lattice point.
This produces one cation vacancy.
No. of cation vacancies = 10-4 mol%
100 mole of NaCI will have cationic vacancy = 10-4
∴ 1 mole of NaCI will have cationic vacancy = 10-4
∴ 100 = 10-6
∴ No. of cationic vacancies
= 10-6 x 6.02 x 1023 = 6.02 x 1017

Solid State & Surface Chemistry - Question 8

Solid State & Surface Chemistry - Question 9

How many unit cells are present in a cube shaped ideal crystal of NaCI of mass 1.00 g?

[Atomic masses Na = 23, CI = 35.5]

Detailed Solution for Solid State & Surface Chemistry - Question 9

Mass of one unit cell = V x d (V is volume, d is density)
= a3 x d

∴ Mass of one unit cell  

 (n = 4 for cubic shape)

= 38.87 x 10-23g

∴  No. of unit cell is 1 

Solid State & Surface Chemistry - Question 10
