Answer:

Formula for Washing Soda is Na₂CO₃ (option c).

Explanation:

Also known as Sodium Carbonate, it is an inorganic compound. Most forms of sodium carbonate have a strong alkaline taste and gives a mild alkaline solution when mixed with water. This water-soluble chemical compound is mostly found white in colour.

Washing Soda is mainly used in the detergent industry to remove dirt and stains on fabrics and hence its name. It is also used in the treatment of hard water.
