Preparation of Silver(i) fluoride: it can be prepared by silver carbonate and hydrofluorineic acid. Firstly, add silver carbonate into platinum dish, then add hydrofluorineic acid to completely dissolve. The whole synthesis process should be kept in dark place.
Uses of Silver(i) fluoride: it can be used as fluorinating agent. And it can be used in organofluorine chemistry for addition of fluoride across multiple bonds. For example, it adds to perfluoroalkenes in acetonitrile to give perfluoroalkylsilver(I) derivatives.
When you are using this chemical, please be cautious about it as the following:
This chemical can cause burns. And it is toxic by inhalation, in contact with skin and if swallowed. When you are using it, wear suitable protective clothing, gloves and eye/face protection and avoid contact with eyes. In case of contact with eyes, rinse immediately with plenty of water or soap-suds and seek medical advice. And in case of accident or if you feel unwell, seek medical advice immediately (show label where possible). Although it is slightly harmful to the water, if without government permission, do not put this material into surroundings.
