Naming Compounds

All acids start with H (e.g. HCl, H 2 SO 4 ) 2 acids types exist: binary acids and oxyacids Binary: H + non-metal. E.g. HCl Oxy: H + polyatomic ion. E.g. H 2 SO 4 Each have different naming rules. Binary acids: naming depends on state of acid If it’s not aqueous: hydrogen + non-metal HCl(g) = hydrogen chloride If it is aqueous: hydro + non-metal + ic acid HCl(aq) = hydrochloric acid (aqueous hydrogen chloride) Naming Acids: Binary acids HBr(s) HI(aq) H 2 S(aq) H 2 S(g) hydrogen bromidehydr(o)iodic acid hydrogen sulfidehydrosulfuric acid

Naming does not depend on the state (aq) 1) name the polyatomic ion 2) replace ate with ic, ite with ous 3) change non-metal root for pronunciation 4) add “acid” to the name E.g. H 2 SO 3 Naming Acids: Oxyacids HNO 2 hypochlorous acid H 3 PO 4 (aq) carbonic acid 1) sulphite,2) sulphous, 3) sulphurous,4) sulphurous acid

a) chloric acid b) hydrosulfuric acid c) hydrobromic acid d) phosphorous acid e) iodic acid f) HCl(g) g) HCl(aq) h) H 2 SO 4 (s) i) H 2 SO 4 (aq) j) HClO 2 k) HF(aq) Assignment: give formula or name a) HClO 3 b) H 2 S(aq) c) HBr(aq) d) H 3 PO 3 e) HIO 3 f) hydrogen chloride g) hydrochloric acid h) sulfuric acid i) sulfuric acid j) chlorous acid k) hydrofluoric acid
