The Cadmium sulfate (1:1), with the CAS registry number 10124-36-4 and EINECS registry number 233-331-6, has the IUPAC name of cadmium(2+) sulfate. It is a kind of white crystalline powder which is highly soluble in water. It is also hygroscopic, and belongs to the follwing product categories: Inorganics; Cadmium Salts; CadmiumMetal and Ceramic Science; Chemical Synthesis; Salts; ACS GradeChemical Synthesis; Cadmium; Catalysis and Inorganic Chemistry; Essential Chemicals; Routine Reagents. And the molecular formula of this chemical is CdSO₄.

The physical properties of Cadmium sulfate (1:1) are as followings: (1)ACD/LogP: -1.03; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -5.53; (4)ACD/LogD (pH 7.4): -5.53; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)#H bond acceptors: 4; (8)#H bond donors: 2; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 82.98 Ų; (11)Enthalpy of Vaporization: 62.94 kJ/mol; (12)Boiling Point: 330 °C at 760 mmHg; (13)Vapour Pressure: 3.35E-05 mmHg at 25°C.

Preparation of Cadmium sulfate (1:1): This anhydrous material can be prepared using sulphuric acid and 30% H₂O₂, And after a series of filtration, crystallization and dehydration, the product is obtained:
Cd + H₂SO₄ + H₂O₂ → CdSO₄ + 2 H₂O

Uses of Cadmium sulfate (1:1): It is used widely for the electroplating of cadmium in electronic circuits. It is also used for electrolyte in a Weston standard cell. And it is also a precursor to cadmium-based pigment such as cadmium sulfide.

You should be cautious while dealing with this chemical. It is toxic by inhalation and if swallowed, and may impair fertility and cause cancer and heritable genetic damage. It is also harm to the unborn child. What's more, it is very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Therefore, you had better take the following instructions: Avoid exposure - obtain special instruction before use; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible); This material and/or its container must be disposed of as hazardous waste; Avoid release to the environment. Refer to special instructions safety data sheet.

You can still convert the following datas into molecular structure:
(1)SMILES: [Cd+2].[O-]S([O-])(=O)=O
(2)InChI: InChI=1/Cd.H2O4S/c;1-5(2,3)4/h;(H2,1,2,3,4)/q+2;/p-2
