'''Cadmium sulfate''' is the name of a series of related ]s with the ] CdSO<sub>4</sub>·{{mvar|x}}H<sub>2</sub>O. The most common form is the monohydrate CdSO<sub>4</sub>·H<sub>2</sub>O, but two other forms are known CdSO<sub>4</sub>·{{frac|8|3}}H<sub>2</sub>O and the ] salt (CdSO<sub>4</sub>). All salts are colourless and highly soluble in water.

==Structure, preparation, and occurrence==
]
] shows that CdSO<sub>4</sub>·H<sub>2</sub>O is a typical coordination polymer. Each Cd<sup>2+</sup> center has ], being surrounded by four oxygen centers provided by four sulfate ligands and two oxygen centers from the ] water ]s.<ref>{{cite journal|author1=Theppitak, C. |author2=Chainok, K. |title=Crystal Structure of CdSO<sub>4</sub>(H<sub>2</sub>O): 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 ]:{{cn|date=January 2022}}
:{{chem2 | Cd + Na2S2O8 -> CdSO4 + Na2SO4 }}

Cadmium sulfates occur as the following rare minerals drobecite (CdSO<sub>4</sub>·4H<sub>2</sub>O), 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 ]. It is also used for ] in a ] as well as a ] in fluorescent screens.
