77998-33-5 - Introduction
Ammonium zinc sulfate hydrate(Ammonium zinc sulfate hydrate) is an inorganic compound with the chemical formula (NH4)2Zn(SO4)2 · xH2O, where x represents the degree of hydration. It is a white crystalline powder at room temperature.
Ammonium zinc sulfate hydrate is stable at room temperature, and will lose crystal water and decompose into ammonium sulfate and zinc sulfate above 80 ℃. It has high solubility in water and can be dissolved in hot water and sulfuric acid with appropriate concentration, but is insoluble in ethanol.
Ammonium zinc sulfate hydrate main uses include:
1. As an additive to the electroplating solution for galvanizing the metal surface.
2. for the preparation of other zinc compounds, such as zinc salt, anhydrous zinc sulfate, etc.
3. Used as a buffer to control the pH of the solution in the laboratory.
The preparation method of Ammonium zinc sulfate hydrate is usually obtained by reaction. A common preparation method is to heat and dissolve zinc sulfate and ammonium sulfate according to a specific ratio, and then cool and crystallize to obtain a Ammonium zinc sulfate hydrate.
About the safety information of Ammonium zinc sulfate hydrate, it is a kind of respirable dust, avoid contact with eyes and skin. Pay attention to personal protective measures during use to ensure good ventilation. At the same time, store in a dry, cool place, away from combustibles and oxidants. In case of any accident, it is still necessary to follow the relevant regulations on chemical leakage and disposal.
