Question

Is baking soda a mixture?

• A. True
• B. False

Answer 1

The correct option is B False

Pure substances can be classified into elements and compounds-

Elements	Compounds
Substances which are made up of the same kind of atoms.	The substances are made up of different kind of atoms.
The elements are not divided into smaller substances by simple chemical processes.	The substances are chemically combined in a fixed ratio.
Example: Carbon$\left(\mathrm{C}\right)$.	Example: water$\left({\mathrm{H}}_2\mathrm{O}\right)$.

Mixtures

Substances where the components are not chemically combined.

The components are physically distinct and separated easily.

Example: Sand and sugar mixture.

Baking soda is nothing but ${\mathrm{NaHCO}}_3$ which is a compound where sodium, hydrogen, carbon, and oxygen are combined chemically.

Therefore, the given statement is false.
