YT2095 Posted July 11, 2006 Author Posted July 11, 2006 Tin is in NO WAY magnetic! never was and never will be.
noel Posted July 11, 2006 Posted July 11, 2006 Keep in mind that tin does not dissolve in hydrochlorid acid at any appreciable rate. A mix of tin and lead probably also does not dissolve easily. PbCl2 is quite insoluble and tin does not react at all with HCl. I tried personally dissolving tin and it is really slow The following may be interesting info: Google groups -- thread on tin Testing whether a piece of metal is lead or tin is easy. Dissolve in conc. HNO3 and then dilute 10 to 20 times. If there is tin in the liquid' date=' then a white precipitate is formed of SnO2. Add a solution of KI to the diluted liquid (whether this contains white precipitate or not does not matter for the test on lead). If there is lead in the liquid, then a beautiful bright yellow precipitate is formed of PbI2. So, in one go you can detect the presence of tin and the presence of lead.[/quote'] Hi there I would like to add that aqua regia is the way to go digesting a solder metal 3 parts HCl and 1 part HNO3 warm gently for around an hour
