Question

5. Which of the following is not a solid solution ?
(a) Ni-Cu
(b) Cu-Zn
(c) NaCl-H20
(d) Fe-C​

Answer 1

Answer:

c................. ...

Answer 2

Answer:

NaCl-H20

Explanation:

The solid solution can be divided into 3 parts:

1. Substitutional Solid Solution
2. Interstitial Solid Solution
3. Ordered Solid Solution

The options a, b, d are solid solution examples like Ni-Cu is an ordered solid solution, whereas the solution of Fe-C is an interstitial solid solution, on the other hand, the second option Cu-Zn or commonly known as Brass is a substitutional solid solution.

The solid solutions are mostly mixtures of solute in the solvent that are formed by the uniform distribution of atom on the crystal lattice.
