Question

2) What conditions are necessary for the formation of a solid solution alloy?

3) Use geometry to show that about 32 percent of a body-centered cubic lattice is empty space.

4) Chromium forms a body-centered cubic lattice in which the edge length of the unit cell is 288 pm. Calculate:

(a) the metallic radius of a chromium atom (b) the density of chromium metal.

Answer 1

Ans 2 :

The solution has 2 basic components : solute and solvent .

Solute is the component in solution which is in lesser quantity , and the solvent is the component of the solution in greater quantity.

While making a solid solution alloy , two basic conditions are important :

Firstly both the solid components must have a similar crystal lattice .

Secondly , the difference in the sizes or the atomic radius of both the components should not be much . It should be less than 15%
