Zinc Hydroxide Chemical Formula
Zinc Hydroxide exists as a rare natural mineral in the earth. It is an amphoteric white solid compound that has the ability to dissolve in a solution of strong acid or base. It occurs as three rare earth minerals Wulfingite, ashoverite, and sweetite.
|Molecular weight||99.394 g/mol|
|Melting point||125 degree Celsius.|
Here is the typical structural representation of Zinc Hydroxide.
It exists in orthorhombic or tetragonal forms.
In normal conditions, zinc dissociates to form zinc ions along with 2 hydroxide ions from the sodium hydroxide solution to form zinc hydroxide.
Zn2++ 2OH- → Zn(OH)2
When Zinc hydroxide reacts with an excess of sodium hydroxide, it precipitates to form Zn (OH)2 and later dissolves into zincate ion.
Zn (OH)2 + 2OH– → Zn(OH)42-
