Question

Explain the formation of NaCl (common Salt) ​

Answer 1

Answer:

A salt is a compound formed from an acid by the replacement of the hydrogen in the acid by a metal. For Ex :In HCl,When H is replaced by Na then we get NaCl. Salts are formed when an acid react a base. The salt of hydrochloric acid are called chlorides.

Answer 2

Answer:

NaCl (COMMON SALT ) :-

• The chemical name of common salt is Sodium Chloride.
• The chemical formula of common salt is NaCl.
• Preparation - HCl + NaOH —> NaCl + H2O.
• Hydrochloric acid reacts with Sodium Hydroxide to form salt that is NaCl.

• Now, particularly let's look at the preparation of NaCl.

• Na (Sodium) = (2, 8, 1).

• Cl (Chlorine) = (2, 8, 7).

• Now, here we have to remove 1 electron to complete the octet of Sodium and we have to get 1 electron to complete the octet of Chlorine.

• Opposite ions helps in the formation of the compound NaCl. (Ionic formation of compounds)

• Hence, the octet also completes.

• Common Salt is obtained from seawater by evaporation.
• It can also be obtained from underground deposits and thus called Rock salts.

Uses of NaCl -

• It is used as raw material in chemical industries. Example - Caustic soda, Sodium bicarbonate, etc.
• It is used in cooking food. It improves the flavour of food.
• It is also required by our body for the working of immune system.
• It is also used as a preservative in pickles.
• It is used in manufacturing of soaps.
• It is also used in melting ice. (especially in cold countries this is used to melt ice collected on roads)
