Sn3(OH)4(NO3)2, tin(II)hydroxide nitrate is described in Gmelin. The substance is unstable and first becomes «Yellow» then «explodes» lightly in storage after a couple of months. Heating to 125 C causes explosive decomposition to SnO2, NO, NO2 and N2O. The compound is more impact sensitive than lead azide and lead styphnate, but less sensitive towards friction. It is said to be very stable towards ignition by sparks. It is barely soluble in cold H2O, hot water causes partial solvation and hydrolysis. A lesser pure form (less pure than the method of Weber using cooling) of it is said to form from adding solid NaHCO3 in small portions to SnO in dilute nitric acid. be carful you made highly sensitive explosive compound!
Very interesting video. I recently found your channel and have been enjoying your content, thanks for making it! During electrolysis and even more at the end, the solution turned yellow. The yellow color looked like it was propogating from the anode. Is this due to some of the stannous ions oxidizing to stannic? Any good way to prevent that or is it unavoidable because of the electric potential?
👍Electronics shop sells "lead free" solder. For environmentally friendly, health conscious hobbyists. 97%tin /3%copper. Try to start with that. Make a big improvement on the amount of tin that you recover.
Awesome demonstration. Thank you, I never knew metastannic is soluble in hot HCl until now. Is your hcl 38%? And why do you not use watch glass (lid) on your beakers when on heat? So much fumes could condense and fall back in when reaction is in progress Another great video as always Picky 👌🏼
Thanks mate. Yeah i didn't know about effectiveness watch glass untill last couple video when my fan damaged do to the nitric acid fumes. Thanks my friend for reminding 😃 I used 30% percent commercial grade HCl but ,The more concentrated the better ... Take care mate.
I produced metastannic acid from tin solder (Sn 99.3% Cu 0.7%) and got a similar slight yellow colour so perhaps it comes from something else, maybe the flux core?
@@PickyPlans one has precipitated gold via AR, and the other is just gold foils that I got from gold plated pins that I use AP for. Actually a 3rd that's from AR as well
This video really intrigued me. Ive always wondered the best way to recover tin from pcbs. This gave me several ideas. Thanks so much for sharing

Interesting ! Thanks referring that.
thank you so much for making the video I asked for, it will help me a lot, thank you sir, greetings from Brazil!
@@PickyPlans Thanks brother, always good to learn new things!

Can I use any carbon or should active carbon during burning

nice 👌
❤️👍👍
If I have metastanic acid in AP or AR how do I get rid of it?

I need help to save 2 different solutions trapped with metastannic acid

Why did you use nitric acid when hcl would have dissolved the solder
You've broadcasting global, Why is three no subtitle ?
