Bryn Posted 16 January 2008 Posted 16 January 2008 I'm resitting Mod 3 Edexcel Chemistry tomorrow and you have to know a load of tests for ions... anyway, the only one I can neither remember nor find on the net is the Magnesium (Mg 2+) ion. Anyone know the test to identify it?
coale39 Posted 16 January 2008 Posted 16 January 2008 The only thing I know about magnesium is that it burns good. This may or may not be of use to you.

Tommy G Posted 16 January 2008 Posted 16 January 2008 I did it to AS level then gave up, it was solid!
Head Honcho Posted 16 January 2008 Posted 16 January 2008 Unfortunately not, with other metals of it's kind burning is the exact way of testing for them, but this is the exception. It does burn in powder form. I remember from my days making Cathode Ray Tubes that the colour of the foreign object in the tube will determine what it is. Glass will create a blue spark, Magnesium a white spark etc etc. I'm a bit sketchy as it was a few years ago but I'm sure you can flame test it
Guest Posted 16 January 2008 Posted 16 January 2008 I did do Chemistry A level, but that was a long time ago. My old textbook only mentions Mg2+ PB2+ salt cells.

Smudge Posted 16 January 2008 Posted 16 January 2008 According to this site it also says its a white preciptate in sodium hydroxide solution
Guest Posted 16 January 2008 Posted 16 January 2008 I hate chemistry. It no longer makes sense to me. I thought it was cooking with chemicals, back in the day. Where's Sir Fynwy when you need him, he's a graduate chemist!
