Which Hydrate Has Ten (10) Water Molecules Bound To It?A. Copper(II) Sulfate Pentahydrate B. Calcium Chloride Dihydrate C. Sodium Sulfate Decahydrate D. Magnesium Sulfate Heptahydrate E. Barium Chloride Dihydrate
Hydrates are an essential concept in chemistry, particularly in the study of inorganic compounds. A hydrate is a compound that contains water molecules (H2O) bound to its structure. These water molecules can be present in various amounts, leading to different types of hydrates. In this article, we will explore which hydrate has ten (10) water molecules bound to it.
What are Hydrates?
Hydrates are formed when a compound reacts with water to form a new compound that contains water molecules. The water molecules can be present in the form of water of crystallization, which is the water that is present in the crystal structure of the compound. Hydrates can be classified into different types based on the number of water molecules present in the compound.
Types of Hydrates
There are several types of hydrates, including:
- Monohydrate: A compound that contains one water molecule per formula unit.
- Dihydrate: A compound that contains two water molecules per formula unit.
- Tetrahydrate: A compound that contains four water molecules per formula unit.
- Pentahydrate: A compound that contains five water molecules per formula unit.
- Hexahydrate: A compound that contains six water molecules per formula unit.
- Heptahydrate: A compound that contains seven water molecules per formula unit.
- Octahydrate: A compound that contains eight water molecules per formula unit.
- Decahydrate: A compound that contains ten water molecules per formula unit.
Which Hydrate has Ten (10) Water Molecules Bound to it?
