A rule or two about polyatomic ions
From –ate…adding an oxygen makes per- -ate…taking away an oxygen (from the original –ate) makes
–ite…taking away another oxygen makes hypo- -ite…
An example:
Base ion →
Hypochlorite
Chlorite
Chlorate
Perchlorate
ClO -1
ClO 2 -1
ClO 3 -1
ClO 4 -1
Taking an –ate and adding hydrogen to it makes “hydrogen –ate” and adds +1 to the charge…adding another
hydrogen makes “dihydrogen –ate” and adds another +1 to the charge…(also works for –ite’s becoming
“hydrogen –ite” or “bi- -ite” by adding one hydrogen or “dihydrogen –ite” by adding two hydrogens)…
An example:
Phosphate
Hydrogen Phosphate
Dihydrogen Phosphate
PO4 -3
HPO4 -2
H2 PO4-1
(sometimes called “biphosphate”)
