free soul Posted November 27, 2008 Share Posted November 27, 2008 I wanna know the lewis structure of these two ions: 1-thiosulfate 2- tetrathionate thank you in advance Link to comment Share on other sites More sharing options...
hermanntrude Posted November 28, 2008 Share Posted November 28, 2008 OK, i've been teaching this recently. Those are two absolute stinkers. However it might help you to know that they're similar to groups of sulfate ions stuck together. It's important to get the formulas of the ions before you start. After that, follow the rules: here's a simple method for drawing lewis structures, although it won't work for some of the harder species it should work for these ions. You might also want to try the tutorial application for sulfate ions here After that, if you still need more (which you might), try googling "thiosulfate ion" and "tetrathionate ion". You'll probably get pages with some lewis diagrams on them... you'll have to check to see if they're complete and correct and even if they aren't they'll help you to some extent. Post again if you're still having difficulties Link to comment Share on other sites More sharing options...
free soul Posted November 28, 2008 Author Share Posted November 28, 2008 thank you so much Mr hermanntrude for your caring try googling "thiosulfate ion" and "tetrathionate ion". You'll probably get pages with some lewis diagrams on them ya , i did .....i found some structures 4 them ...hope that they are true to get the 5 marks as our instructor said... thanx again Link to comment Share on other sites More sharing options...
hermanntrude Posted November 28, 2008 Share Posted November 28, 2008 that's not what i suggested. It'd be much better if you could draw it first and then look it up afterwards to see if you got it right. Make sure you know how to draw Lewis structures. when you come to be tested you won't have google any more. Link to comment Share on other sites More sharing options...
