CHEMISTRY PART 9 Acids and Bases. Acids  A compound that makes hydrogen ions when dissolved in water.  H + (aq)  Look for the (aq) (which means aqueous)

Naming Acids and Bases. Bases contain an OH group C 6 H 12 O 6 does not have an OH group If an OH group is present it will be clearly indicated: e.g.

Chapter 20.  Objectives: List the properties of acids and bases Name an acid or base when given the formula.

Acids and Bases And neutralization reactions. Acids and Bases An acid is a substance that produces hydrogen ions in solution. HCl  H + + Cl - A base.

 Acid  A compound that produces hydrogen ions (H + ) when dissolved in water  An ionic compound Cation = H + Anion = monatomic or polyatomic ions Only.

Naming Acids and Bases. Binary Acids (two elements) Recall: All acids contain a hydrogen ion (H + ). Binary Acids are compounds made of H + and a non-metal.

Acids and Bases. An acid is a compound that dissolves in water to form a solution with a pH lower than 7. A base is a compound that dissolves in water.

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 (H2SO4)

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) H2Se(aq)

Oxyacids Naming does NOT depend on the state Name the polyatomic ion Replace –ate with –ic or… Replace –ite with -ous Change non-metal root for pronunciation Add “acid” HBrO4 HIO2 (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
