paired with Br- Cl- I- No3- SO4^2- CO32- C2H3O2
No3- and C2H3O2-
chloride bronide iodied unless theywwre with mercury (hg) silver (ag) lead (pb)
(so4)^2- not soluble when its with slm or sr ba ca
(co3)^2- and (po4)^3- they are only solible with alkali metals (group 1) or ammonium NH4+
Oh- and S^2- onyl soluble with alkali metal and ammonium and ca sr ba -alkanine earth metals
group 16,17 and non metals for single anipns
when ion has higher number of oxygen atoms oxyanion No3 or SO4 or Po4
lower number of oxygen atoms in oxyanion serios NO2 or SO3 or PO3
per is for on mroe oxygen then ate and hypo for one fewer than ite
