Naming Acids and Bases Chapter 9

Acids… Contain one or more H + when dissolved in water Anion combined with as many H + as needed to make the molecule neutral Two types of acids 1. Binary: H + non-metal (HCl) 2. Oxyacid: H + polyatomic ion (H 2 SO 4 )

Binary Acids Form when certain gaseous compounds dissolve in water Naming depends on state of acid HCl (g)  hydrogen chloride If it is dissolved in water (aq)  hydro- (nonmetal root) -ic acid HI (aq) HCl (aq) H 2 Se (aq)

Oxyacids Naming does NOT depend on the state 1.Name the polyatomic ion 2.Replace –ate with –ic or… 3.Replace –ite with -ous 4.Change non-metal root for pronunciation 5.Add “acid” HBrO 4 HIO 2 (perbromate) (iodite)

Bases Ionic compounds that produce OH - when dissolved in water Follow same rules for naming ionic compounds NaOH Ca(OH) 2 Fe(OH) 3
