Sodium Carbonate

Sodium carbonate (also known as washing soda, soda ash, sal soda, and soda crystals) is the inorganic compound with the formula Na ₂CO ₃ and its various hydrates. All forms are white, odorless, water-soluble salts that yield alkaline solutions in water.

Sodium carbonate is a key ingredient in laundry detergents as it helps to remove dirt, grease, and stains from fabrics It works by softening hard water and allowing the detergent to work more effectively Additionally, sodium carbonate acts as a buffering agent, helping to maintain the pH balance of the detergent solution This property helps to prevent the detergent from becoming too acidic, which could damage the fabric being washed.

Sodium carbonate is also used in the manufacturing of soap. It is added to the mixture of fats and oils to increase the alkalinity of the soap This reaction, known as saponification, produces soap and glycerol.
