We use many different household chemicals everyday, and one of the most common is sodium carbonate (Na2Co3.) Classified as a sodium salt, its chemical formula resembles everyday baking soda. However, baking soda is not toxic, whereas sodium carbonate is caustic, which makes it an excellent cleaning ingredient.
Although used in many household cleaners, sodium bicarbonate is also a common ingredient in stain removers. Also known as 'soda ash,' it has high alkalinity, and is a common additive to laundry detergents. Outside of the house, sodium bicarbonate is used in glass production, as a pH regulator during film developing, as an abrasive in toothpastes and even as a food additive in minute amounts.
Sodium bicarbonate offers solutions to many of our everyday modern needs, but it can be harmful if ingested or left in contact with bare skin. This chemical can also irritate or damage eyes and the upper respiratory tract if inhaled.
