Sodium Carbonate is an odourless, white powder. It is the disodium salt of carbonic acid and when dissolved in water forms carbonic acid and sodium hydroxide.

Alkaline in pH and with the principle element of sodium, sodium carbonate is commonly referred to as washing soda or soda ash and is used principally in the manufacturing of glass. Sodium carbonate is also used in the processing of wood pulp to create paper, to manufacture soaps and detergents and is a well-known chemical used for water softening applications. It is also used in the food and beverage, textile industry and as a chemical pH adjuster.

FAQs

What is the difference between sodium carbonate and sodium bicarbonate?

Sodium carbonate and sodium bicarbonate are two different chemical compounds with different chemical properties and formulas. Sodium carbonate possesses a high pH and is used predominantly in industrial processes such as detergent, glass and paper manufacturing whereas sodium bicarbonate has a lower pH and used mainly in baking and antacid products.

Why is sodium carbonate called washing soda?

Sodium carbonate is often referred to as 'washing soda' because it has traditionally been used as a laundry aid. When dissolved in water it reacts with greases and soils making them easier to remove. It is also able to soften the hardness of water.
