Yes, I know I was a bit in hurry... But I asked my teacher now and he said that I could do it with pH=2 also on the column, but I have to re-neutralize the column every day... Thanks for your help!

Yeah and then maybe titration, but we have to use modern analytic methods like HPLC etc. I found some papers... Does anyone has free access to papers like this: - quantifying via GC - it would be very appreciated. I already got this one: - quantifying via HPLC -, but I guess our HPLC doesn't have such column. Merged post follows: Consecutive posts mergedhm well, I got all papers now... I have decided to use HPLC with a gradient (oH-level ~2) Because you need something which prevents the ascorbic acid of degrading to dehydroascorbic acid. You can achieve this with substances which block the oxidizing of Ascorbicacid or a acid like metaphyophoric acid which also safes the ascorbic acid.

Hey I have searched in the internet, but I didn't find anything related to that. I found how to extract the hot substances like gingerol. But I didn't find anything for ascorbic acid. So does anyone has an idea? I want to quantify the amount of vitamin C in ginger. It is for a project work at school. Any suggestion is welcome!

interesting, thank you. I saw it in the first post too now,

hi cool video, what was the last thing. Al + FeO? I just understood something with very hot iron... Or could someone clarify this for me, the reaction and it's reactants? thx

Could it be, that this is working, because the mixture takes the water out of the fat...? And it'll really look thinner. But as longer as you may try it and stop from one day to another, your body reminds that there was a high need of water and maybe you get much more fat on the area where you put this mixture, because your body still supplies the water. just an idea. But better do sports and eat some fibres.

it's workin again!

Does this also affects IRC? I tried blackcobalt and opressess.us, but no answer? cheers

Does this also effects the ircserver? I tried blackcobaldt and opressess.. no connection? cheers

Hi Does anyone know, if there is a database( would be good in sql-schema or in a schema which is easy to convert to sql), which is free for download. Just for basic compounds and their molweight, boiling point, etc?

Theo.. its your turn!

@ alien.. there is a xchat version which hasn't a 30day trial -> -Xchat free version -, maybe you update your post.

oh ya..... I tried to choose a simple one, but maybe that was the mistake, I know that there were more then one possible answer... anyways formic acid is correct! Sorry alien, I was very tired when I posted this... but I really don't know.

yeah right! But you should give the next compound... nevermind here is the next and who guess this right has to give the next... H2SO4: ---------- You can find this quite weak acid in very small animals which have a big own state with a queen... they are known as to work in a group and they can carry a multiple of their own weight. So which acid is it!?
