Electrolytic Tin

Growing tin crystals from a stannous chloride solution in hydrochloric acid. The loop of wire they are growing from (cathode) is stainless steel while the thing in the upper lefthand corner (anode) is a chunk of 95/5 tin/antimony electrical solder wrapped in filter paper to catch the bits of antimony that drop off as the tin dissolves. THIS IS IN REAL TIME! No fast forward, no editing. Sorry it's a bit fuzzy and the color is a tad off.

Hi! how much is the potential taht you apply?

[WinterSurvival]

The source I'm using is rated 16V at 4A. The rate of growth of the metal is solely dependent on the amperage though, as long as the voltage is sufficient to reduce the tin (II) ions to tin metal. Based on standard redox potentials, this is only about 0.14V.

Hi,

how can I make tin (II) chloride? Can I put powder tin in HCl acid (32%)? If I mixed that what I get, tin(II)chloride? thanks.

[WinterSurvival]

Yes, tin powder in HCl will get you Tin (II) chloride. You need to have an excess of HCl present though, since extra acid stabilizes the compound in solution.

Is it possible that you do the same thing, but with silver insted of tin?

[WinterSurvival]

Probably not. Unlike Tin (II) chloride, silver chloride is insoluble, although it can be dissolved by several complexing agents. However, adding them simply makes the electrochemistry even more complicated since they often can be oxidized or reduced instead of the metal. Silver sulfate is likewise very poorly soluble, although silver nitrate is a possibility. I can't comment on crystals though. Often times, you get blackish powdery deposits of the metal.

Lead acetate, however, works nicely.

so you could take a pile of newer penny's and scratch each one then make sure they are touching an electrode while in the paper bag thing, making sure to get through the copper outer layer and exposing the Zn core. then if you made the solution and applied voltage you could get a pile of zinc?

[YippieKayYa33]

could you do this experiment using copper wire instead of stainless steel

[demnlordd666]

that is bad ass!

@WinterSurvival Ever since college , I'd been extremely self conscious and uncomfortable about my personal darkish, facial hair on my upper lip as well aschin. Waxing by no means worked and Iswear bleaching made additional hair grow. That is precisely why I tried the product bit.ly\uVlBLX and its really changed my entire life. you should certainly check it out for.

[jucest]

how to you identify a tin metal from other metals that have similar color and appearance ?

[kuro96inlaila]

Very beautiful crystal!

Is the crystal strong enough to be hold?

[69iron69]

cool

[imaqtlolz]

real time?
