Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]
A colorful example is cobalt(II) chloride, which turns from blue to red upon hydration, and can therefore be used as a water indicator.. The notation "hydrated compound⋅n H 2 O", where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated.

Two polymorphs are known as pentahydrate. The anhydrous salt exists in several polymorphs. [2] In the solid state, the thiosulfate anion is tetrahedral in shape and is notionally derived by replacing one of the oxygen atoms by a sulfur atom in a sulfate anion. The S-S distance indicates a single bond, implying that the terminal sulfur holds a ...
Bismuth(III) nitrate is a salt composed of bismuth in its cationic +3 oxidation state and nitrate anions. The most common solid form is the pentahydrate. [3] It is used in the synthesis of other bismuth compounds. [4]
Borax "pentahydrate" has the formula Na 2 B 4 O 7 ·5H 2 O, which is actually a trihydrate Na 2 B 4 O 5 (OH) 4 ·3H 2 O. It is a colorless solid with a density of 1.880 kg/m 3 that crystallizes from water solutions above 60.8 °C in the rhombohedral crystal system .

The pentahydrate Th(NO 3) 4 •5H 2 O crystallizes with clear colourless crystals [6] in the orthorhombic system. The unit cell size is a=11.191 b=22.889 c=10.579 Å. Each thorium atom is connected twice to each of four bidentate nitrate groups, and to three water molecules via their oxygen atoms. In total the thorium is eleven-coordinated.
