Solubility in water (g/100ml) Dissolved grams per 100ml of water at different temperatures (℃):
85.9g/0℃;120g/10℃;172g/20℃;190g/30℃;203g/40℃
Production method
1. put silver carbonate into the platinum dish and add 40% hydrofluoric acid to completely dissolve it. The solution is placed on a water bath to evaporate, then transferred to a sand bath, stirred with a platinum spoon and evaporated until dry. The purity of the obtained product is 92% to 95% (containing 5% to 8% of Ag2O). The whole synthesis process should be carried out away from light.
2. electrolyze glacial acetic acid solution containing 7% potassium fluoride without direct light irradiation, using a silver plate or silver rod as anode and platinum wire as cathode. Pole. The current during electrolysis should be greater than 40 mA. The silver fluoride generated on the anode falls loose from the electrode and collects at the bottom of the electrolysis vessel. The product was filtered out, washed with glacial acetic acid and anhydrous benzene, and then placed in a vacuum dryer to remove the stained benzene at room temperature, with a 99.5% yield. With 20 volts and 120 mA current, 0.5 grams of fluorinated forceps can be obtained within 60 minutes.
Category Corrosive Substances

| production method | 1. Silver carbonate was placed in a platinum dish, and 40% hydrofluoric acid was added to completely dissolve it. The solution was evaporated on a water bath, then transferred to a sand bath, stirred with a platinum spatula and evaporated to dryness. The purity of the obtained product was 92% ~ 95% (containing 5%~ 8% of Ag2O). The entire synthesis process should be carried out in the dark. 2. The glacial acetic acid solution containing 7% potassium fluoride was electrolyzed to avoid direct irradiation of light, using a silver plate or silver rod as anode and platinum wire as cathode. Electrolysis current should be greater than 40 mA. The silver fluoride formed on the anode was loose from the electrode and collected at the bottom of the electrolysis vessel. The product was filtered off, washed with glacial acetic acid and then with anhydrous benzene, and then placed in a vacuum dryer at room temperature to remove the adherent benzene in 99.5% yield. With a voltage of 20 volts and a current of 120 mA, 0.5g of a fluorinated clamp was obtained in 60 minutes. |
