Question

The trivial name of ${ Na }_{ 2 }{ CO }_{ 3 }$ is?
(A) Soda ash
(B) Soda carb
(C) Soda
(D) Baking soda

Answer 1

Hint: It is a high soluble substance and used for numerous chemical reactions and mostly used as an ingredient in the manufacture of dyes and coloring agents, synthetic detergents and fertilizers.

Complete step by step answer:
It is a white powder which is prepared by ${ Na }_{ 2 }{ CO }_{ 3 }\cdot 10{ H }_{ 2 }O$ , which is a decahydrate of Sodium Carbonate more popularly known as Washing Soda.
On heating washing soda it loses its water of crystallization and gets converted to its monohydrate and above 373K, the monohydrate further breaks down to form a completely anhydrous white powder which is $Na_2CO_3$ , known as Soda Ash. It has a strongly alkaline taste and gives moderately alkaline solutions in water.
Soda ash has a number of uses that touch our lives every day. Glass manufacturing is the largest application for soda ash whether it is in the production of containers, fiberglass insulation, or flat glass for the housing, commercial building, and automotive industries. Household detergents and paper products are a few other common examples of readily identifiable products using soda ash.
Hence, the trivial name of ${ Na }_{ 2 }{ CO }_{ 3 }$ is soda ash. Therefore, option A is the required answer.

Note: Soda ash is mildly alkaline and will happen to dissolve in human perspiration, which could lead to mild skin irritation in individuals with sensitive skin, particularly in hot and humid conditions.
