making nitric acid

[YT2095]

nope, most drain cleaners are alkaline, but some patio/path cleaners contain HCL

damn its back to finding some old car batterys or a company that service batteries which is probably near impossible

[boris_73]

ok then where could i find some old cheap batterys

[Gilded]

That kno3 looks great, but still, it's in USA. And jsatan, oh how I tried! But all the sellers are in USA. Recently, I mailed to an American pyrotechnics company and I think they thought I was a freaking terrorist or something.

[YT2095]

a local junk yard with scrap cars in it, they normaly keep the batts next to the office/shed

[boris_73]

did you get your conical flask from scichem.co.uk if so how much did it cost

[boris_73]

i forgot to ask as well your condenser which you made do you push it through your cork, most probably do thats what i am going to do and also why do you put you tube which is bent into the acid i thought it would be placed just above it

no its not in the USA did you not look at the prices there in pounds£ not dollars$ which means its in england

[Gilded]

Whoops! I just saw "Cleveland" and thought it was Cleveland, Ohio. But apparently it's the state of Cleveland in England.

 

Edit: Hmm, it's got "the strongest ammonia money can buy" and iodine crystals on the same page. Time for some nitrogen tri-iodide!

[boris_73]

"i saw cleveland" but still the currancey would have given the country away nevermind ill let you off and we dont have states we have countys i i was thinking that but £40 for the ammonia im sure you can get it cheaper else where

[YT2095]

did you get your conical flask from scichem.co.uk if so how much did it cost

I did, they`re only up the road from me, and I bought a box of 10, I don`t rem the cost as it was a few years ago and the invoice is long hidden in a pile of paperwork since then, sorry.

[boris_73]

its not good enough again back to the distilling the long tube you made(condensor) did you put it through the cork because thats what i will do and why did you put the tube in the acid not above the acid

[YT2095]

through the cork then sealed up.

 

IN because the vapors will condense better when bubbled THROUGH the acid rather than above it. and THAT will HAVE TO BE "Good enough"

[boris_73]

i see where you are coming from thats brilliant thank you now all i need is the sulphuric acid

[YT2095]

the acid`s cheap as chips and plentifull, you shouldn`t have a prob

[boris_73]

which acid the one i posted in H2O2

[YT2095]

no... the H2SO4 that we`ve been discussing in here all day

[boris_73]

or right yes i will look around for some

[boris_73]

have you looked at http://www.growell.co.uk and typed in nitric acid in the search button

[YT2095]

indeed I have, and I`m pretty disgusted that you`ve known this and not once asked how to concentrate it

[boris_73]

i am really sorry but like i said in the H2O2 post i thought it would have some really bad impurites to concentrate it though could i just boil it or would i have to distill it and besides i have learnd something from it one how to make nitric acid from potassium nitrate and sulphuric acid and two if i know of a link mention it at the start

[boris_73]

so how would i concentrate 38% nitric acid to 70% would i just boil it or would i distill it and that nitric acid i mentiond would it have some impurites

[YT2095]

add conc sulphuric to it and re-distill it, that`s all I do, just keep an eye on the gas color (or temp if you want to get fancy) LOL

[boris_73]

does'nt that give you a concentration of about 98% because i only want 70% 98% is way to concentrated, couldnt i just boil it. and won't that nitric acid from the ph down have impurities or would it just be nitric acid and water

[YT2095]

I`ve no way of knowing what impurities the PH Down has without having a sample, so I can`t really answer that for you in honesty, but re-distilation will elliminate them unless they have a lower BP, but even so, it`ll shift most
