Sandy,
Thanks for the details. I am sure many will benefit from them. I told myself
last summer that I was going to try carbon this winter, but I am not sure if I
can get to it due to other works. Maybe I should go to Montana to take a class
from you. :) It will be a chance to meet Judy too. Oh, but I think the times
are not the same since it's a whole summer program rather than a short period
of time like APIS.

What is the concentration of the stock solution? Is it saturated? I am still
trying to figure out why my dichromate solution precipitated (and it
precipitated badly. You can clearly see a layer of brown precipitates). As I
said, I am suspecting the change of saturation point due to temperature, but
it could be other reasons.
And I must confess my sin here. I did not use distilled water in preparing my
dichromate solution. :P :) That could be the main problem too.
