Question

What are the ways to remove soluble impurities from water ? Explain them.

Answer 1

Answer:

Many ways are using which you can easily separate water from soluble and insoluble impurities.

Some of the methods to separate water are,

1)    Distillation

2)    Precipitation

3)   Ion exchange.

In distillation, the water is separated using simultaneous heating and condensation.

Precipitation is the process in which the solid is made to settle at the bottom of the beaker.

A saturated solution is formed to separate crystals of the impurities from the solution.

Answer 2

Evaporation is the process used to remove soluble impurities from water

Explanation:-

• Soluble impurities are components that can be dissolved in water.
• Solubility occurs under dynamic equilibrium
• In this the sovent goes through a dissolution phase with a solute , creating suspended molecules of ions in the solvent.
• Insoluble impurities in water include sand, clay, total suspended solids and orgaic matter etc. , these do not dissolve in water.
• Soluble impurities can be removed by evaporation or distillation.
• While insoluble can be removed by sedimentation, filtration or decantation.
