Its awesome!

Greetings what reducing agent do I need to use so I can do this without using heat?

[charmenk]

wow! a whirpool in the beaker?! o.O'

i want a magic beaker!

[george456789]

Does it have to be heated for the silver to precipitate? For eg the ammonia is being driven off by heat, could you put a vacuum in the flask which will drive off the ammonia too? Or is heat required?

i did it it was beautiful but had to be done for around 25 minutes .really very tedious 4 our lab atleast

[mu7champions4ever]

tks 4 the vid. very helpful!!

[somervillefire]

i did something like this in highschool but on a much larger scale. also, i used dextrose and didnt have to heat it. i still have the 250mL flask with the silver lining the entire inside of it.

just speak ya pussy

[Bernler75]

Can it be another alternative to make silver for jewellery?

[jpthecreaton]

would have been really cool to have heated the solution on a flat peice of glass...still fun,though

[johnson039039039]

thx dude, i've studied this reaction in chemistry textbook but never watched one,

so cool for the silver mirror formation.

btw, u do it at home?

so cool u got those apparatus

i love chemistry but my home is too small and those apparatus are just too expensive..

Hmm... I did this without adding Glucose to the solution in my school laboratory, but it still works. Any idea why?

Thanks for uploading this mabakken! Been trying figure this whole procedure out for a while now and finally got it with this vid. Very nice job

[mossydie]

If I had one of those automatic stirrer thingies I would use it to make tea just for the hell of it...

Nice vidoes, very professional feel to them.

[mabakken]

I did it! It was awesome!

[rjo281]

@mossydie Hopefully not after you used it in lab ;)

[RicarDDini]

after heating

[mabakken]

Well, the Silver is supposed to precipitate after heating, but on the glass. Try cleaning the glass properly. Get back to me if it still doesn't work :)

[RicarDDini]

I tried it but the silver only percipated...

[mabakken]

At what stage of the experiment did the Silver Precipitate?

[adriankocian]

I like your "experiments" can you add more videos to learn me something? :D:D thankx

[adriankocian]

How have you cleaned it? :D:D:D

[mabakken]

By introducing a dilute solution of Nitric acid :)
