Ok its Monday, I need 500ml of 0.1% Acetic acid,
0.1% 500ml of citric Acid
& 0.1% 500ml of Ascorbic acid.
and my head is at home.
0.1%
Re: 0.1%
0.1% = 0.1 grams per 100mL (Mass/volume)
so for citric and ascorbic acid, weigh out 0.5 grams, dissolve in 500mL.
For acetic acid you will need to work out what % acetic acid you have in your stock solution. Glacial , according to the laboratory is18M at 99 -100%, so my calcs, 2M should be 11%, so 4.5mL of 2M up to 500mL.
If my calcs are totally off, someone let me know.

Re: 0.1%
Hi,
i couldn't get in to the Preparation of 0.1% acetic acid.
In our lab we have 80% acetic acid. How can we prepare 0.1% in 500ml. Can someone explain it little more further??
I can't think as i am brain dead today:-(
