Hello to all
I have bought a new lot of Dichromate Ammonium, but their aspect is
different to the one that I use. It is not crystallized. It is powder. I
check that in the label says "moistened with 0,5-3,0% of H2O PRS. I
imagine that I will be able to use it, but the solution will no longer
be same.
For example: i make solution to 15%, but now..... what quantity of
dichromato and waht quantity of water to make the same solucition to 15%?.
Thank you and pardon for muy English, text translated by computer.
