Definition and Uses :
Zinc (II) chloride, also known as zinc butter, is an inorganic salt that is very soluble in water and is often used as a catalyst and disinfectant in organic synthesis.
Zinc chloride is often thought of as an ionic compound, but it has been determined that it has a more covalent behavior. Zinc chloride can react in a variety of ways, all similar to the reactions shown by covalent compounds: for example, complex formation with the water molecule or the formation of complex species such as Zn ( OH) 3 Cl 2- , Zn (OH) 2 Cl 2- or ZnOHCl 2- in the presence of alkaline solution.
Zinc comes after iron, aluminum, and copper in terms of annual usage in the world.
