It's wrong cuz there is concentrated nitric acid. Also, you get NO2 as brown gas.
No, sir, the formula is right, because we don't have nitrogen oxide in the reaction, which is colorless and odorless. Our gas is brown and smells like car exhaust and is called nitrogen dioxide.
Why fool around with thermometers? . This just in: 200 + mercury switches from Ebay, total cost around 12 euro. Containing around 80 grams of mercury, from my calculations. It will be a bit of a pain in the ass to get it out of there, but I'm a busy bee . I'll just crush them up in a plastic container and filter out the mercury through a filter paper with a small hole in it.
I've been looking at these Mercury switches on Alibaba and they don't look like they are any big. Can there really be around 3 grams of mercury in one?
I don't know how much theoretically is needed to amalgamate 12gr of Al, could not find equation online but it seems extremely small.
G.Patton said:Approximate ratio is from 1:1300 up to 1:650 (mercury(II)nitrate to Al in moles).
Pennywise said:This is a relatively large range, with 50g Al this would be an amount from 0.4g to 0.9g
Hi, i tried this step, but when i added the nitric acid to the mercury, nothing happened. the concentration of my nitric acid is not very high, so i added a greater amount. i left it for quite a long time now but nothing happened, so i wanted to ask if you guys maybe have an idea, why that could be. thanks a lot

You can't evaporate water from nitric acid aq solution, you have to carry out distillation only. Also, be careful because NO2 can explode during this procedure, avoid open fire.concentrate it by evaporation
Wahrscheinlich gibt es einige Hg(NO3)2, die in Wasser gelöst sind. Ich denke, Sie haben eine schwache HNO3-Wasserlösung. Dazu müssen Sie konzentrierte Säure verwenden.
Sie können kein Wasser aus wässriger Salpetersäurelösung verdampfen, Sie müssen nur eine Destillation durchführen. Seien Sie auch vorsichtig, da NO2 während dieses Vorgangs explodieren kann, vermeiden Sie offenes Feuer.
You have to use concentrated acid for this purpose.
what concentration yould be the minimum and is there any way to get a higher concentration without distilling? i dont have that much glassware and i really dont want to spill boiling nitric acid so i would like to avoid that method. if that doesnt work, can hydrochloric acid be used to form mercury chloride? what would be the equation for that and what concentration of hcl would be needed? thanks so much
Thanks for the information, I wasn't aware of that!
Is it possible to extract water from the acid with MgSO 4 my general .... ???
Is there a way to get the reaction going with l ow concentration? High temperature should Speed the reaction Up, would that bei enough? Or any Kind of catalyst? Thanks so much
But did you miss my question? It's vital.
What concentration of nitric acid do you have?
Im really sorry my nitric acid hast 0.5mol/l i think thats 0.3%, Higher percentages are difficult to get h ere die to explosive regulations, thank you so much for your help, your the best
