Hello guys .......
First of all let me explain what i did........basically i put around 70 computer ram fingers in AP solution , i get the foils , than i dissolve them in HCL+ Bleach(4-1 ratio) , so i get orange solution . I let it settle for day to get the clorine out of my solution ,then i test it with stannous chloride and show me a positive response (Black) then i add copperas for precipitation , i saw a reaction and white salt was formed in the bottom of container and nothing happen......then i let it settle for 20 days then i tried the copperas in small sample and the solution turn into bright green + some white salt.....is the problem with my copperas so should i use another precipitattion method, or do i still have clorine in my solution ?
NB: i was made my copperas with diluted sulfiric acid + iron from transformer , let it settle for night in closed pot, then i get the green crystal , which i dissolve them in hot water + few drop of HCL.
