What is the Difference Between Washing Soda and Soda Ash?

Washing soda and soda ash are both sodium carbonate, but they have different forms and uses. In reality, there is no significant chemical or physical difference between the two, as they refer to the same chemical compound and have the same formula, Na2CO3. The main differences between washing soda and soda ash are:

1. Form: Washing soda is the decahydrated form of sodium carbonate (Na2CO3.10H2O), while soda ash is the anhydrous form of sodium carbonate.
2. Production: Soda ash is dissolved in water, and when crystallized, it forms washing soda.
3. Uses: Both washing soda and soda ash are used as cleaning agents, but they have different applications. For example, washing soda is commonly used in laundry and dishwasher detergents, while soda ash is used to raise pH and total alkalinity in swimming pools.

In summary, washing soda and soda ash are essentially the same chemical compound but have different forms and applications.

Comparative Table: Washing Soda vs Soda Ash
