Answer 2

Evenly dissolved

Question 3

Saturated solution

Answer 3

Contains the maximum amount of solute for the volume of a solution at a particular temperature.

Question 4

Unsaturated solution

Answer 4

When there is less amount of maximum solute that has been added to the solvent.

Question 5

Concentration=

Answer 5

n/V(in Litres)

Question 6

Process of crystallisation

Answer 6

A technique that is used to isolate substances and is based on the difference in solubility between two temepratures.

Question 7

Unit for concentrationn

Grams per litre

Question 8

ppm formula

Answer 8

mass of solute in micrograms/mass of solution in crams

Question 9

Formula for %(m/m)

Answer 9

mass of solute in g/ mass of solution in g x 100%
