Question

State two properties of washing soda.

Answer 1

1. Washing soda is a transparent crystalline solid.
2. Washing soda is one of the few metal carbonates which are soluble in water.
3. A solution of washing soda in water is alkaline and turns red litmus to blue.
4. Washing soda has detergent properties (or cleansing properties) because it can remove dirt and grease from dirty clothes, etc. Washing soda reacts with dirt and grease to form water-soluble products, which are then washed away during rinsing with water.
