Louey Posted June 22, 2004 Share Posted June 22, 2004 I'm doing a balanced chemical equation for the reaction that occurs when solid barium hydroxide dissolves in water. Have I done this right (sorry not yet got to grips with the subscripts so saying subn when I need to!) Ba(OH)sub2 --> Ba2OHsub2 If I have gone the wrong way can someone direct me where I have gone wrong so I can understand what I am not doing. Thank you Link to comment Share on other sites More sharing options...
budullewraagh Posted June 22, 2004 Share Posted June 22, 2004 not technically correct. rewrite as Ba(OH)2 --> Ba2+ + 2OH- Link to comment Share on other sites More sharing options...
Hero Posted June 25, 2004 Share Posted June 25, 2004 when those elements are combined with water, they simply become ionized and the bonds between the barium and hydroxide are ripped apart. Link to comment Share on other sites More sharing options...
dryan Posted June 26, 2004 Share Posted June 26, 2004 Ba(OH)2 --> Ba2+ + 2OH- Correct, but by putting (s) and (aq), it tells the reader that the material is in the solid form or in the aqueous form. Link to comment Share on other sites More sharing options...
Bryn Posted June 26, 2004 Share Posted June 26, 2004 why not just put [math]Ba(OH)_{2(s)} + (aq) \rightarrow Ba(OH)_{2(aq)}[/math]. Far simpler and does exactly what is says on the tin. Link to comment Share on other sites More sharing options...
JaKiri Posted June 26, 2004 Share Posted June 26, 2004 why not just put [math]Ba(OH)_{2(s)} + (aq) \rightarrow Ba(OH)_{2(aq)}[/math']. Far simpler and does exactly what is says on the tin. Because that's not what the homework requires; whilst it's adequate shorthand, it's useless for establishing a grounding in the mechanisms of aqueation.

budullewraagh Posted June 26, 2004 Share Posted June 26, 2004 both imply the same thing. it's like drawing organic compounds the notation C-C-C implies propane. the notation H H H H-C-C-C-H H H H also implies propane. both are accurate. both mean exactly the same thing.

budullewraagh Posted June 26, 2004 Share Posted June 26, 2004 eh pretend that second propane structure actually worked... Link to comment Share on other sites More sharing options...
Louey Posted June 28, 2004 Author Share Posted June 28, 2004 reading through this is actually very helpful so thank you for continuing this thread - I've got some compounds to figure too lol Link to comment Share on other sites More sharing options...
Sayonara Posted June 28, 2004 Share Posted June 28, 2004 eh pretend that second propane structure actually worked... If you use the [code/code] BB tags, you can make a block of monospaced text. All characters will take up the same horizontal space, and spaces will not be collapsed. Handy for things like propane structure Link to comment Share on other sites More sharing options...
