anhydriittinen

Anhydriittinen refers to a substance that is anhydrous, meaning it lacks water molecules. In chemistry, this term is often used to describe a salt or compound that has lost its water of hydration. For example, anhydrous copper sulfate is a white powder, whereas hydrated copper sulfate is blue. The removal of water can be achieved through heating or by using a drying agent. Anhydrous substances are important in various chemical processes, such as reactions where the presence of water would interfere with the desired outcome. They are also used as drying agents themselves, as they readily absorb moisture from their surroundings. The term "anhydriittinen" is the Finnish equivalent of "anhydrous."
