Washing soda is a chemical compound with the chemical formula Na2CO3.10H2O. It is also known as sodium carbonate Washing soda is a whitish, odorless powder that is alkaline with a pH level of 11. It is one of the few metal carbonates that are soluble in water. Its unique chemical composition makes it effective at degreasing and deep cleaning clothes. However, because of its high pH level, washing soda is caustic and should never be touched with bare skin.
