Answer Details
When sodium trioxocarbonate (IV) decahydrate loses its water of crystallization to the atmosphere, the process is called efflorescence. This is a process by which a hydrated compound loses its water of crystallization, usually due to exposure to air, resulting in a dry, powdery substance. In this case, sodium trioxocarbonate (IV) decahydrate, also known as washing soda, loses its ten molecules of water of crystallization to the atmosphere, resulting in the formation of anhydrous sodium carbonate.
