Question

which separation techiques will you apply for tge separation of soium chloride from its solution in water


pls. pls Urgent ​

Answer 1

$\LARGE{ \underline{ \bf{Required \: answer:}}}$

Sodium chloride is common salt or table salt which is actually formed by the neutralisation process of Hydrochloric acid and Sodium hydroxide.

It is soluble in water and can be separated by the process of Evaporation where the water gets evaporate leaving the salt behind because Sodium chloride is not volatile.

Refer to the attachment for the process.

In large scale, You might have seen Evaporation process being done in shallow pits near sea shores because sea water is 5-6% saline. The salt obtained is purified and refined to produce the salt that can be consumed.

There are many such separation techniques used in separating or purifying the substances like:

• Crystallization
• Sublimation
• Sedimentation & Decantation
• Filtration
• Separating funnel
• Distillation
• Chromatography
• Centrifugation etc....

Answer 2

Sodium Hydroxide is commonly known as caustic soda.

The chemical formula of sodium hydroxide is NaOH.

Sodium Hydroxide is very important basic chemical which is used as a starting material for making many other chemicals.

It is used in many industries and hence produced on large scale.

Sodium hydroxide is produced by the electrolysis of a concentrated aqueous solution of brine.

hope it helps....
