'''Cadmium sulfate''' is the name of a series of related [[inorganic compound]]s with the [[chemical formula|formula]] CdSO₄·{{mvar|x}}H₂O. The most common form is the monohydrate CdSO₄·H₂O, but two other forms are known CdSO₄·{{frac|8|3}}H₂O and the [[anhydrous]] salt (CdSO₄). All salts are colourless and highly soluble in water.

==Structure, preparation, and occurrence==

[[File:EntryWithCollCode100316.png|thumb|left|Portion of structure of CdSO4 illustrating the distorted tetrahedral geometry at Cd (dark blue spheres).<ref>{{cite journal |doi=10.1524/zkri.1980.0011|title=A Reinvestigation of the Crystal Structures of HgSO₄ and CdSO₄|journal=Zeitschrift für Kristallographie - Crystalline Materials|year=1980|volume=153|issue=1–2|pages=121–129|bibcode=1980ZK....153..121A|last1=Aurivillius|first1=Karin|last2=Stålhandske|first2=Claes}}</ref>]]

[[X-ray crystallography]] shows that CdSO₄·H₂O is a typical coordination polymer. Each Cd²⁺ center has [[octahedral coordination geometry]], being surrounded by four oxygen centers provided by four sulfate ligands and two oxygen centers from the [[bridging ligand|bridging]] water [[ligand]]s.<ref>{{cite journal|author1=Theppitak, C. |author2=Chainok, K. |title=Crystal Structure of CdSO₄(H₂O): A Redetermination" |journal=Acta Crystallographica Section E|year=2015|volume=71|issue=10 |pages=i8–pi9|doi=10.1107/S2056989015016904|pmid=26594423 |pmc=4647421 }}</ref>

Cadmium sulfate hydrate can be prepared by the reaction of cadmium metal or its oxide or hydroxide with dilute sulfuric acid:

:{{chem2 | CdO + H2SO4 -> CdSO4 + H2O }}

:{{chem2 | Cd + H2SO4 -> CdSO4 + H2 }}

The anhydrous material can be prepared using [[sodium persulfate]]:{{cn|date=January 2022}}

:{{chem2 | Cd + Na2S2O8 -> CdSO4 + Na2SO4 }}

Cadmium sulfates occur as the following rare minerals drobecite (CdSO₄·4H₂O), voudourisite (monohydrate), and lazaridisite (the 8/3-hydrate).

==Applications==

Cadmium sulfate is used widely for the electroplating of cadmium in electronic circuits. It is also a precursor to cadmium-based pigment such as [[cadmium sulfide]]. It is also used for [[electrolyte]] in a [[Weston standard cell]] as well as a [[pigment]] in fluorescent screens.
