HC104, perchloric acid: KC1O4, potassium perchlorate. 



HClOs, chloric acid: KClOs, potassium chlorate. 



HClOs, chlorous acid: KC1O2, potassium chlorite. 



HC1O, hypochloTous acid: KC1O, potassium hypochlorite. 



Salts derived from the hydrogen acids, such as HC1, 

 HBr, EbS, contain but two elements and follow the rule 

 in 1 (a) rather than that of 3; thus CaCk, from hydrochloric 

 acid, is not called calcium hydrochlorate, but is termed 

 calcium chloride.
