Equation of State
An equation that describes the behavior of matter in a given state, the van der Waals equation describes the behavior of the gaseous state.
Coordinate Covalent Bond

Phosphoric Acid
H3P04, Colorless liquid or rhombic crystals, decomposes before it will boil. Used mostly in the metal etchant. Used in cleaning operations to remove encrusted surface matter and mineral scale found on metal equipment such as boilers and steam producing equipment. Also used to brighten metals and remove rust.
