Steve M asked:


I’ve been playing around with the creation of hydrogen through electrolysis almost immediately after applying a current to my electrodes, a green looking sludge begins spilling out from them, floating to the top. Sometimes little chunks of stuff come out too, resembling spices in a pot of boiling liquid. There is also an orange/rust colored sludge that begins to form as well. I am using stainless steel electrodes, as I have been told they are very effective and I am using a battery charger as my power source. Any ideas?

Ammonium dichromate (NH4)2CR2O7 which exist as orange crystals, may be decomposed upon heating according to the following reaction:
(NH4)2Cr2O7 - Cr2O3 + N2 + 4H2O

How many grams of orange crystals are needed to produce 4.58g of water?
I saw your reply Dennis , it was very helpful so i tried my way

what i did is this:

252 x 4.58 / 72
= 16.03

which gives the same answer, is that the right way ?
