Nitric Acid
Hello guys,
I'm wondering how to make nitric acid at home
I thought KNO3 + H2SO4 = KHSO4 + HNO3
Please tell me how dangerous and toxic,and complicated this process is.Is there any other ways to make nitric acid,not using precursors.
What I actually need is to dissolve mercury,only way I know is with nitric acid.
Tell me if there is others way to dissolve mercury,I heard mercury dissolves in concentrated H2SO4.
Thanks for help.

This is organic chemistry so this thread will almost certainly be moved.
Nitric acid is a walk in the park compared with mercury nitrate, which is soluble in water and extremely toxic.
It is also a Schedule 1 poison in the United Kingdom.
I would not do mercury chemistry at home. In my opinion it is far too dangerous.
Most professional laboratories only use mercury or mercury compounds if there is no alternative.

I need something that can dissolve mercury liquid,you know one from old thermometers,sulfuric acid wouldn't work ? what conditions should be kept ?
Or anyone can recommend website that sells Hg salts preferably (no3),ones that sells without license.
Anyway is Hg salts precursors ?
P.s. sorry for English ..

Mercury is dissolved by oxidising acids so H<sub>2</sub>SO<sub>4</sub> must be hot, concentrated!
Even dilute (>5%) cold nitric acid will dissolve Hg to form the mercurous(I) compound but I would heed SS's timely warning if I were you -
all mercury compounds are toxic, some even by contact!
If the fulminate is your target then extensive reading on the subject is pretty much essential . . .
[edit]
The reaction of Hg(NO<sub>3</sub> <sub>2</sub> with EtOH is
extremely vigorous, producing copious quantities of toxic gasses!

hissingnoise what you mean by hot?92-94% H2SO4 is enough ?
If >5% would work,I think something like pH minus would work?Or can you recommend anything else that would dissolve mercury that can be bought OTC?
I know how toxic mercury is..

Just I know how to handle it and have conditions to work with it,so is there any products that sold OTC that contain nitric acid with % enough to
dissolve mercury,all I can think of is pH-minus,but I can't find any that tells % of nitric acid ..

You are asking some naive questions that indicate a lack of the knowledge and experience needed to work with mercury compounds.
Handling mercury salts safely on a preparative scale requires a good fume hood and a decontamination and disposal strategy.
I would not handle mercury compounds in my shed or garden.
They are just too hazardous.

Well I have fume hood.Yes I know my knowledge of chemistry is not best but,can you just tell me what products contains nitric acid that would dissolve
mercury.Which sold OTC

Why do you want to dissolve mercury?

So! You have the metal, but before using it to form the amalgam, you're going to convert it into one of its salts . . .
Er, WTF!

You'd use a Mercury salt to coat copper for illegal gold mining. Of course you're totally uninterested in making an aluminum amalgam...

Yea course you do. I suggest you give up before you end up poisoning either yourself or others. How about making some pretty copper sulfate crystals
instead?

Wow guys I can't believe you are so funny 
Are you just trolling me or what ?
I worked before with Hg(II) dehydrated and now im out of it .. Anyone could really help instead of trolling me.

Because you need aluminium amalgam for what kind of reduction I wonder? You seem so clueless about whole situation that I dont think its really all
that safe you playing with soluble mercury salts... perhaps you can prove otherwise.
