Silver nitrate - silver nitrate, or, as it is also called, lapis, has the form of transparent, completely colorless crystals. In shape, they resemble small sticks that dissolve well in water, and just as easily in alcohol. It is worth noting that the substance darkens under the influence of light, and is not compatible with iodides, bromides, organic substances and chlorides at all.
Silver nitrate in medicine

Silver nitrate is used in small amounts for anti-inflammatory and bactericidal action, but you should be careful with silver, because direct contact with silver leaves black spots on the skin, and prolonged contact causes burns.
The most commonly used silver nitrate in the treatment of warts. Although the best results can beachieve in the case of small warts. Sometimes, of course, they try to cauterize with lapis and large ones, but this process is not always effective - relapses often occur.

But like everywhere else, there are "buts". First, you must have nitric acid (HNO3) and a silver item. Spoons, forks, chains, rings and other products are suitable from silver. The next process is simple. It is necessary to place the selected silver item in a glass of nitric acid. The reaction will follow immediately. Silver will immediately begin to darken under the action of acid, small bubbles of gas will begin to form. It is possible that during the oxidation process the color of the liquid itself will change - this indicates that there were some impurities in the silver. If you want the reaction to happen faster, then place the beaker of the solution in hot water.
Now we take out the silver object, and put the remaining solution in the refrigerator for half an hour to precipitate. After the allotted time, we take out the formed crystals of silver nitrates, filter and leave them to dry. That's the whole process of making silver nitrate.
