Question

Differentiate between a homogenous and a heterogeneous mixture with one example of each in the (a) solid-solid (b) solid-liquid If (c) liquid-liquid state of the mixture.

Answer 1

Homogenous mixture

1. Constituents – uniformly mixed.
2. Properties and composition the same throughout the mixture.
   Example: Alloys, (salt + water), air, etc.

Heterogeneous mixture

1. Constituents – not uniformly mixed.
2. Properties and composition not the same but vary throughout the mixture.
   Examples: (oil + water), (iron + sulphur).
   Solid – solid homogenous mixture is brass (Cu + Zn)
3. Solid – solid heterogenous mixture is (iron + sulphur)
