Hydrate
Hydrous refers to a substance that contains water molecules within its molecular structure. This term is often used in mineralogy to describe minerals that have water molecules incorporated into their crystal structure.
Ice is the most organized state of water because the molecules are arranged in a crystal lattice structure. This structure creates a more organized and rigid arrangement compared to liquid water or water vapor.
Evaporation, it is called sublimation.
Exactly what it says. Some compounds incorporate water molecules into their crystals. These water molecules are called "water of crystallization." Heating such crystals often drives off the water through evaporation, which is an example of the loss of water of crystallization.
Crystal beads grow bigger when they come into contact with water due to a process called hydration. Water molecules are absorbed by the crystal beads, causing them to swell and increase in size. This interaction between the water molecules and the crystal beads results in the expansion of the beads.
Water that is an integral part of the crystal structure is referred to as water of crystallization. This water is bound within the crystal lattice and is essential for maintaining the crystal structure.
That rather depends on how it is trapped. You are probably thinking of water of crystallization, where water is a constituent part of the crystal structure, such as in CuSO4.5H2O, hydrated (blue) copper sulfate.
When a crystal gives off water vapor and turns into a powder upon heating, it typically indicates that the crystal is a hydrated salt (contains water molecules within its structure). The heating drives off the water molecules, leading to the breakdown of the crystal structure and formation of a powder.
There are two main theories of water of hydration. One theory is the hygroscopic theory, which suggests that water molecules are loosely bound to the compound through hydrogen bonding. The second theory is the lattice theory, which proposes that water molecules are incorporated within the crystal lattice structure of the compound.
Water of crystallization
This process is called dissolution. Water molecules surround the individual ions of the salt crystal, separating them from the crystal and forming a solution.
Complex crystal structure and hydrogen bonding
NaCl salt does not contain water of crystallization.
Ice is a type of solid crystal with a hydrogen bond structure. The bonds between water molecules in ice are hydrogen bonds which are weaker than covalent or ionic bonds. The crystal structure of ice is hexagonal.
It's called methyl clathrate, a clathrate compound which consists of methane trapped within a crystal structure of water similar to ice.
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
