hi every one, i have ferric chloride etchant solution to prepare from 2.5kg of hexahydrate grannule. i tried experimenting with little quantities mixture of water and the hexahydrate grannule in ratio 2 to 1 respectively. then i dip copper board into it and after 4hrs etching had not started. please what is the best way to prepare ferric chloride etchant solution
Should have worked. How clean was the copper? Temperature of the solution sometimes effects etching time. Usually takes about 15 minutes, but sometimes during the winter months it takes 30 minutes or so. Four hours, and nothing, bad chemicals, maybe something in the water. Really can't say, its not complicated to add power to the water, concentration isn't critical.

Mixing strong chemicals requires attention to detail to avoid getting killed.
"hisyam" has demonstrated his competence by seeking Fe3Cl by dissolving Fe (or is it really Cu) in HCl. Or maybe he has dissolved Fe in sulfuric acid and is seeking to get Fe3Cl by mixing the solution with HCl. He has 2.5kg of something called "hexahydrate grannule". I have no clue what this is, but I get a quarter million hits on google which link hexahydrate with home made explosives.
Perhaps this would-be chemist should be approached with caution.
