Question

Method used for separating sodium chloride from its solution

Answer 1

Explanation:

by water evaporation or mixing aluminium chloride

Answer 2

Answer:

By the process of

1. boiling
2. distillation

Explanation

1. for getting the solute only-boiling

we will heat the solution of sodium chloride. As we know that the solution of sodium chloride is a mixture so it will show the the properties of its constituent that is water and salt and the the properties of water to boil on hundred degree Celsius .So as soon as the temperature will reach at hundred degree Celsius water start boiling and salt will remain unboiled so we will get the sodium chloride

2. for getting solute and solvent both -distillation

first we have to arrange the distillation appratus then we will put the solution of sodium chloride in the distillation flask .As soon as we start heating the solution water form vapour (steam) which rise up and come out through the side tube of the distillation flask and then it will go into water condenser .Cold water from the tap is circulated through the outer tube of condenser for cooling the vapour. The hot vapour get cold in the condenser to form pure water which trickles down from the condenser and collect in the beaker. The pure water is then called distilled water. The salt remain in distillation flask only
