KNOW CHLORATE Once you know chlorate then you know 12 polyatomic ions because bromine and iodine behave similar to chlorine |
ClO3^-1 OXYANION ENDING IN '-ATE' |
|
|
Anion with a charge of -2 or -3 is considered highly charged because... |
- It can reduce it's overall charge and become more stable by adding a positive H+, which forms a polyatomic ion - These anions are named by adding 'hydrogen' or 'bi' (i.e. bisulfate or hydrogen sulfate) |
|
|
Sulfate + H+ = |
HSO4^- SO4^2-+H= (bisulfate or hydrogen sulfate) |
|
|
Sulfite + H = |
HSO3^- SO3^2-+H= bisulfite or hydrogen sulfite |
|
|
Carbonate + H = |
HCO3^- CO3^-2+H= bicarbonate or hydrogen carbonate |
|
|
Phosphate + H = |
HPO4^2- OR H2PO4^- PO4^3- + H = hydrogen phosphate OR dihydrogen phosphate |
