Answer 2

Answer:

(c) Washing soda

Explanation:

The nature of Washing soda is a base. The chemical name of washing soda is sodium carbonate and the chemical formula is $Na_{2}CO_{3}$. It acts as a base because when washing (sodium carbonate) reacts with water it dissociates into a strong base (NaOH) and a  weak acid (carbonic acid). Washing soda is an inorganic compound which is formed by the reaction of a strong base and weak acid. So, washing is a base.
