Zinc HydroxideSodium Nitride, Formula, Chemical Properties, Preparation, Application

Zinc Hydroxide

Zinc hydroxide is an inorganic compound that has the white powder in the appearance. It contains three rare minerals such as wulfingite, ashoverite and sweetite. Zinc hydroxide have the properties of reacting two compounds such as bases and acids. When it is exposed to the strong acid the insoluble hydroxide is dissolved. The systematic IUPAC name is known as zinc hydroxide. The chemical or molecular formula of zinc hydroxide is Zn(OH)2.

Structural Formula

This is the structural formula of the zinc hydroxide:

Zinc Hydroxide

Chemical Formula

The chemical formula of the zinc hydroxide is Zn(OH)2.

Preparation Method

The zinc hydroxide is prepared by adding the zinc salt with the sodium hydroxide solution to form. Because the zinc is cations and hydroxide is anions and it formed the equal concentrations. When the precipitation of zinc hydroxide is dissolved the sodium hydroxide is added at a large quantity for leaving the colourless zincate ion solution.
