Sodium carbonate, commonly known as soda ash or washing soda, is a white, powdery substance that is highly soluble in water. It has a variety of uses, including in the production of glass, where it helps to lower the melting point of silica. Additionally, it is often used in laundry detergents to enhance cleaning power and soften water. In households, sodium carbonate can be found in many cleaning products due to its ability to remove stains and grease. It is also used in swimming pools to help maintain proper pH levels, ensuring the water remains clean and safe for swimming.
