Question

The question contain terms which require stating their meaning. In this case, for each question, their meaning should be stated. 

Answer 1

In solvent extraction, different solubilities of two liquids makes them unable to mix to form a homogenous solution. Different solubilities, for example, makes two liquids form two layers and makes it possible to employ solvent extraction technique. 

A salt is said to be hydrated when it contains water molecules between its particles or crystals. 

Adding a solute to a solvent forms a solution in the cas of a polar solute and polar solvent. Maintaining the same temperature, there reaches a certain point upon which the solvent cannot take in more of the solute. At this point, the solvent issaid to be saturated. 

a) Solvent extraction- is a technique used to separate the components of a mixture based on their solubility in different solvents.
b) Hydrated salt - salt that contains water of crystallization.
c) Saturated solution - solution which no more solute can dissolve into it.
