Title: How can you tell the charges of polyatomic ions? Post by: _biology on Sep 8, 2012 Do you just have to memorize them? Or is there a way to figure this out?
Title: How can you tell the charges of polyatomic ions? Post by: lexi68 on Sep 8, 2012 Basically you need to just memorize.
You can find patterns in some of the polyatomic ions. For example: sulfate = SO4^2- sulfite= SO3^2- If you ever need to name an acid by looking at an equation like H2SO4 = SULFURIC ACID SO4 is sulfate= anything with -ate is -ic acid H2SO3 = SULFUROUS ACID SO3 is sulfite= anything with -ite is -ous acid I hope this helps with something :) |
