For monatomic ions see p 57 of the text.
You must know the names, formulas, spellings of all of these polyatomic anions.

The red ones are especially important and serve as a basis for other related ions.

"Hydrogen" anions (HPO4-2, HCO3-, etc.) follow a systematic pattern of naming and charges
derived by adding H+ to the base anion from the table below.

CO3 -2 carbonate          

NO2 - nitrite 
NO3 – nitrate

 

 

 

PO3 -3 phosphite 
PO4 -3 phosphate 
   

SO3 -2 sulfite
SO4 -2 sulfate                     

ClO - hypochlorite  
ClO2 - chlorite
ClO3 - chlorate
ClO4 – perchlorate

 

AsO3 -3 arsenite
AsO4 -3 arsenate
   

SeO3 -2 selenite
SeO4 -2 selenate                    

BrO - hypobromite  
BrO2 - bromite
BrO3 - bromate
BrO4 – perbromate

 

 

 

IO - hypoiodite  
IO2 - iodite
IO3 - iodate
