(a)
Interpretation: The name of the technique for the separation of table salt and pepper is to be interpreted.
Concept introduction:
A mixture consists of two or more components that can be physically separated into their respective components. The mixture can be categorized as homogeneous or heterogeneous depending on how uniform it is.
There are several separation techniques used to separate the components of the mixture. Some common examples of separation techniques are evaporation, distillation, fractional distillation, etc.
