Specification

The Silver, with the cas registry number 7440-22-4, is a kind of white glossy metal. This chemical is soluble in nitric acid, hot sulfuric acid while insoluble in water. Besides, it is stable but incompatible with strong acids and strong bases, tartaric acid, oxalic acid. In addition, it will be blackened by contacting with ozone, hydrogen sulfide, sulfur.

The production method of this chemical is below: Prepare the silver as the raw material and then dissolve it in the nutric acid to make the electrolyte with the component of Ag 50 g/L，HNO₃3～10 g/L; Next add into the electrolytic cell to electrolysis with the temperature of 45℃, cell voltage of 2.5 V, current density cathode of 2.5～2.7 A/cm². Lastly, have the electrolysis and refining to get the high purified silver products.

As to its usgae, it is widely applied in many ways. It could be used as the electronic industry material and in the preparation of high purified silver salt and high purified analysis reagents; It could also be used in gelled propellants, catalytic agent, adsorbing material, promoting agent, and then in filter, carbon-film potentiometer, solid tantalum capacitor, Darlington and heating element; In addition, it could also applied as the material in electroplate and preparation of precision alloy and solder.

When you are using this chemical, you should be very cautious. For one thing, it is harmful which may cause damage to health and it is irritating to skin. For another thing, it is toxic which may at low levels cause damage to health. If by inhalation, in contact with skin and if swallowed, it will be very dangerous. Besides, it has limited evidence of a carcinogenic effect. In addition, it is dangerous for the environment which may present an immediate or delayed danger to one or more components of the environment. Besides all these, it is flammable and may causes burns.

Due to so many dangers above, you should take the different measures to deal with different cases. Wear suitable protective clothing, gloves and eye/face protection. And if in case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) Then remember to avoid contacting with skin and eyes. In addition, do not breathe vapour.

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [Ag]
(2)InChI: InChI=1S/Ag
(3)InChIKey: BQCADISMDOOEFD-UHFFFAOYSA-N
