Question

Fill in the blanks: Formula of sodium carbonate is.......................... and that of ammonium sulphate is...................…

• A. ${\mathrm{Na}}_2{\mathrm{CO}}_3$
• B. ${\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4$

Answer 1

Sodium carbonate (${\mathrm{Na}}_2{\mathrm{CO}}_3$):

1. Sodium Carbonate is an inorganic compound; it is commonly known as Soda ash.
2. It is extracted from trona.
3. Trona is a double salt-containing Sodium Carbonate (${\mathrm{Na}}_2{\mathrm{CO}}_3$), and Sodium Hydrogen Carbonate (${\mathrm{NaHCO}}_3$) formed due to the series of evaporation processes at lakes.

Ammonium Sulphate${\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4$:

1. Ammonium Sulphate is non-hazardous to humans.
2. It is also known as Diammonium sulfate or Sulphuric acid diammonium salt
3. It has no smell and dissolves in water easily. It does not dissolve in acetone.
4. It appears as a crystalline solid white and has a salty taste.

Hence, the formula of Sodium carbonate is ${\mathrm{Na}}_2{\mathrm{CO}}_3$, and that of Ammonium sulphate is ${\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4$.
