Question

CaS04 is a crystalline solid. Which of the following is not a property of it?
(A) It melts at a particular temperature
(B) Each Caz• ion is surrounded by a particular number of SO~- ions.
(C) The force of attraction between Ca2• and SO~- is uniform throughout the solid
(0) II's physical properties are uniform throughout the solid

Answer 1

Answer:

Anisotropy: Crystalline solids are anisotropic in nature, that is some of their physical properties like electrical resistance or refractive index show different values when measured along different directions in the same crystal. This arises from different arrangement of particles in different directions arrangement of particles along different directions

Explanation:

So I think the answer will be B) Each Caz• ion is surrounded by a particular number of SO~- ions.
