i have looked into the argos book and it appers they no longer sell those type of chemistry sets only worm farms fossils making strange plants and volcanoes etc.

thank you very much i always wanted to know what were in those chemistry kits as well

what eg. £1 will get about $1.40 how many dollars do you get to your Kuwait denar if its more then thats news to me well saying that nearly everything british has changed mainly due to the world war and europe

i dont think so unless its a new law but i dont buy large amounts i rarley use it if so its yt who should be worrying

where could i buy some methyl orange

lucky bugger!

im not botherd about you supplying it but where do you get yours from my next door neighbours a farmer so if i ask him he just gives me about a couple of kg which lasts me months,he is a brilliant neighbour

potassium/sodium nitrate and ammonium nitrate is also sold at http://www.gardenchemicals.co.uk just thought you might want to know thats where i got my first batch of potassium nitrate

whats 25kg sacks at kno3.com and i know we over pay we have the highest currency in the world you can also get potassium/sodium nitrate, ammonium nitrate from http://www.gardenchemicals.co.uk i mentiond this in the black powder forum

thanks and ill be looking forward to hearing who does and who does'nt sell to the public

where do people get there glassware from eg conical flasks in the UK, both from web sites and shops, what companys

mercury switches are no longer made out of mercury its know some non toxic chemical shame

well at http://www.kno3.com its £9.00 for 25 meters they also sell magnisuim powder there

does anybody know where to buy mercury

budullewraagh when you are making nitric acid from potassium nitrate and sulphuric acid does'nt water mainly come out for the first 5 minutes or so then the nitric acid comes out. i suppose i could test it with a ph indicator strip

lol. thats at A-level and thats minimum you would also stand a better chance if you did some other activity as well

there are three more things how much sulphuric acid should i add to the nitric acid and where did you get your glass rods from and what temperature should i heat the homemade nitric acid using potassium nitrate and sulphuric acid these are the last thing's i am going to ask and thank you for helping me

i'll be vice chairman

you still havent answerd my question though you should become a politician do i have to add the sulphuric acid to get 70% conc i am pretty sure you dont but i just want to check

if the bottle is 1 litre and it`s 38% nitric' date=' how many bottles are needed to make 1 litre of 70% nitric?

 

 

c`mon dude, use your head! you`ll be asking me to make it for you next! [/quote']

i dont want 1ltr exactly i should have said but i would rather have more then less. 2 bottles would be suffice all though at a £5 delivery charge i might just buy 5 bottles that way i wont have to keep paying £5 if i want some nitric acid i'll have enough to last me a long time

use yts method or mine you get more oxygen much quicker a lot more oxygen

why do you want them any way the electrolysis method doesnt work very well i have tried it

suprisingly, im having difficulty getting some graphite rods anywhere, i live in london, UK, can anyone suggest a shop which would sell them?

use the pencil leads burn of the wood and just use the pencil leads the thicker the pencil the better

if you run a current through water you will release hydrogen and oxgen which is also used as a rocket fuel in liquid form (not water) similar to liquid oxygen now if you mixed does gases together you would probably/absolutly get more of a kick then standard petrol or desiel but to produce enough for the car to run would require alot of energy

yes but i want about 1ltr of the nitric acid and considering about 62% of its water possibly something else it only leaves me with 380ml which is enough but not enough for different experiments. so should i add the sulphuric acid or would distilling it without the sulphuric acid give me my 70% conc acid
