The video describes an experiment involving the creation of an amalgam, particularly focusing on the reaction between sodium and ammonium. The experimenter began by discussing the unique reactions of different metals and decided to create a series of videos about them. The initial video involved sodium and mercury, resulting in a rapid reaction that generated heat and solidified some of the mercury. The reason for starting with sodium was its potential to serve as a gateway to other amalgams, including ammonium amalgam.
To create ammonium amalgam, the experimenter used a process outlined in a 1865 paper, which involved combining sodium amalgam with ammonia solution and hydrochloric acid. The resulting reaction seemed to involve redox reactions between sodium and ammonium ions. The amalgam was observed to undergo various changes, including expansion, shrinking, and reactivity. It was also affected by factors like temperature and the presence of specific salts.
The experimenter attempted different variations of the experiment, including cooling and heating the amalgam, observing its behavior underwater and in an open environment, and examining its texture. Ultimately, the experiment concluded with the hope of definitively confirming whether an ammonium amalgam had been formed.

2. The reaction between sodium and mercury was extremely fast, generating a lot of heat. [Source: Document 1](https://www.example.com)
3. The sodium melted almost instantly, sometimes splashing and igniting. [Source: Document 1](https://www.example.com)
4. Most of the sodium was dissolved, and its concentration in the mercury slowly rose. [Source: Document 1](https://www.example.com)
5. The speaker decided to make both liquid and solid forms of the amalgam. [Source: Document 1](https://www.example.com)
6. The speaker chose sodium as the starting point for this series because it can be used as a gateway to other amalgams. [Source: Document 1](https://www.example.com)
7. The speaker found a paper from 1865 that outlined the general process of making ammonium amalgam. [Source: Document 1](https://www.example.com)

10. The sodium metal wants to give up an electron, and the ammonium ions accept it. [Source: Document 1](https://www.example.com)
11. The ammonium ions lose their charge and become neutral, and the sodium metal becomes sodium ions. [Source: Document 1](https://www.example.com)
12. The sodium ions are quickly pushed out of the mercury and combine with the chloride anions in solution to make sodium chloride. [Source: Document 1](https://www.example.com)
13. The ammonium radical, which is now neutral, seems to dissolve into the mercury in its normal ionic form. [Source: Document 1](https://www.example.com)
14. The speaker noticed that if the sodium amalgam bubbled for a while before adding the acid, the results were different. [Source: Document 2](https://www.example.com)
15. The speaker found that keeping it cold or letting it pre-expand at room temperature were both decent ways to make the amalgam. [Source: Document 2](https://www.example.com)
16. The speaker tried adding the amalgam to a solution of ammonium chloride and found that it stayed a lot more flat. [Source: Document 3](https://www.example.com)
17. The speaker decided to stop heating it and tried adding more ammonium chloride. [Source: Document 3](https://www.example.com)
18. The speaker found that the amalgam kept most of its shape as it expanded when the solution was added to it. [Source: Document 3](https://www.example.com)
19. The speaker concluded that some sort of ammonium amalgam does form, but it has never been confirmed. [Source: Document 3](https://www.example.com)
