We continue the topic of chemical experiments, as we hope that you will definitely like them. This time we present to your attention another fascinating experience, during which we will receive a silver mirror.
Let's start by watching the video
We will need:
- capacity;
- silver nitrate;
- hot water;
- ammonia solution of 10%;
- glucose;
- alcohol burner
Let's start with silver nitrate. We take about a gram from it and dilute it in a small amount of hot water.
Next, we add sodium hydroxide to the resulting solution. During this reaction, silver oxide forms, which precipitates.
Next, pour a 10 percent ammonia solution into the silver oxide precipitate. The ammonia solution must be poured until the precipitate dissolves.
Silver ammonia is formed during this reaction. Add 5 grams of glucose to the resulting solution.
Now you need to heat the resulting mixture. To do this, light an alcohol burner and put a glass on it so that the mixture gradually heats up. During this reaction, a very large amount of ammonia is released, so this reaction must be carried out either under the hood or on the street. During the reaction, silver nitrite can also form, which is a very dangerous substance, so the dishes should be thoroughly washed after the reaction.
After some time, a thin layer of silver gradually begins to settle on the walls of the glass. The reaction ends about 15 minutes after the start of heating.
In order to get a more even layer of silver, you need to put a glass with the mixture in a large container, pour it into a container of hot water and put it on an alcohol burner. Thus, the temperature will be distributed evenly and the result will be more effective.
