heptahydraatti
Heptahydraatti refers to a crystalline solid that contains seven molecules of water per molecule of the anhydrous compound. This water is incorporated into the crystal lattice structure and is known as water of hydration. The presence of these water molecules significantly influences the physical properties of the compound, such as its melting point, solubility, and density, compared to its anhydrous form.
Many common salts can exist as heptahydrates. A well-known example is sodium sulfate decahydrate, often called
The number of water molecules in a hydrate is indicated by a prefix. "Hepta-" signifies seven. Other
