0.1%

[Labbie]

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.

[curie]

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.

Thank you Curie, Mad monday

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:-(

My chem teacher uses C1V1=C2V2 for any concentration calculation.
so:
0.1%x 500 = 80% x V2

So I think the volume would be 0.625ml in 500ml
