This is a simple displacement reaction. The copper coil will displace silver from silver nitrate out of solution to form silver metal. Hence, the grey/silver coating being formed on the copper coil. At the same time, the copper atoms at the surface of the copper coil is being oxidised to copper(II) ions slowly turning the solution into a blue solution. Hence, the light blue-ish colour appearing first around the copper coil and then slowly increasing in concentration till the whole solution turns from colourless to blue.

1. Soon after the wire is dipped, flecks of something (contaminants?) drop off of the spring. 2. Also, copper nitrate makes the immediate area around the wire gain a blue tint, and later produce a shimmer effect. And, after removing the copper, It is *red*. Reminds me of once I put a penny in with salt and vinegar for days. Some of them gained pits. Others turned red or black. The same solution also hardened Elmer's glue.

You can see around 3:00 where the density (and thus the refractive index) is changing due to the shift of ions. It's the slight shimmering, the same as can be seen on the hood of a car in the summer or above an asphalt road.

You can make your own silver nano-particle silver heat sink compound with silver nitrate... When you expose finely ground silver nitrate to UV light it reduces the silver nitrate to silver nano-particles. A UV EPROM eraser lamp works perfect then you just mix the silver nano-particles with a small amount of silicone oil to make a paste like consistency mixture. The massive surface area of the silver nano-particles combined with silvers excellent thermal transfer properties make it a terrific heat sink compound. It efficiently fills the microscopic hills and valleys in the metal heat sinks surface allowing the heat to transfer as effectively as possible. More is not better either! The thinnest possible layer is the best, just make sure it's enough to fully cover the surface, a couple 1000ths is all you need...

@chemx85919 жыл бұрын
No it wouldn't work. Elemental silver precipitates out of the soulution because copper is a less "noble" metal than silver (redox potential). It is therefor oxidized by the silver ions and goes into solution, whereas the silver ions are reduced to elemental silver. It wouldn't work the other way round, because copper has a lower redox potential as silver. Effectively what you end up with after all the silver precipitates is the case you mentioned (elemental silver in a copper nitrate solution) and as you can see nothing happens there.
@mrhomescientist9 жыл бұрын
ChemX is right. Search for the 'reactivity series' or 'activity series' - elements higher on the list will displace elements lower on the list from their solutions. You'll see copper is above silver, so this reaction can proceed but the reverse won't. You need a more active metal than copper, like iron or aluminum.
@Kisven9 жыл бұрын

Kisvenlucky7 Yeah, and also consider this: If the reverse reaction ( copper nitrate + silver -> copper + silver nitrate ) were possible, then the reaction in the video wouldn't hapen either!

@mrhomescientist9 жыл бұрын
+William Law To determine if it's endothermic, you'd have to look up the reaction enthaplies for all the compounds in this reaction. The beaker doesn't noticeably change temperature, so it's probably a small value either way. If you look at the reaction's equation, the 1g of silver metal I aimed to produce only consumes 0.29g of copper (due to silver's higher molecular weight and it's coefficient of 2 in the equation). So with such a relatively big wire, that small amount of copper isn't noticeable as a change in thickness.
