I have used bleach to make rust(with salt), how can I seperate the rust from the salt?
I was looking for a way to make rust (ironoxide) and found that bleach coul be used as an oxidizer; however, I would not know when it was finished breaking down. With some research I found that NaClO + H2O2 -> O2 + NaCl + H2O. I think I can use this to either: use the NaClO and make the ironoxide, then add the H202 to break do the residual NaClO (extra H2O2 can be evaporated with the H2O), or used the reaction to speed up the ironoxide making with a bit of extra H2O2 to insure all the NaClO is used and the evaporate off the rest. (which would be better? would be my first question, but not the most pressing one) My question is how can I sepperate the Iron oxide from the NaCl (salt), since both are water soluble (sp)? A filter will seperate out larger pieces of ironoxide, but there will still be a fair amount that passes through the filter with the salt and I would like to minimize my loses as much as possible.
