2 Acids Arrhenius acids produce H + ions in water. H 2 O HCl(g) H + (aq) + Cl - (aq) are electrolytes. have a sour taste. turn litmus red. neutralize bases.
3 Names of Acids Acids with H and a nonmetal are named with the prefix hydro and end with ic acid. HClhydrochloric acid Acids with H and a polyatomic ion are named by changing the end of the name of the polyatomic ion from ate to ic acid or ite to ous acid. ClO 3 − chlorate HClO 3 chloric acid ClO 2 − chlorite HClO 2 chlorous acid
5 Select the correct name for each of the following acids. A. HBr 1. bromic acid 2. bromous acid 3. hydrobromic acid B. H 2 CO 3 1. carbonic acid 2. hydrocarbonic acid 3. carbonous acid C. HBrO 2 1. bromic acid 2. hydrobromous acid 3. bromous acid Learning Check
6 A. HBr3. hydrobromic acid The name of an acid with H and one nonmetal uses the prefix hydro and ends with ic acid. B. H 2 CO 3 1. carbonic acid An acid with H and a polyatomic ion is named by changing the end of an ate ion to ic acid. C. HBrO 2 3. bromous acid This acid of bromite (BrO 2 - ) is bromous acid. Solution
7 Bases Arrhenius bases produce OH − ions in water. taste bitter or chalky. are electrolytes. feel soapy and slippery. neutralize acids.
8 Some Common Bases Bases with OH - ions are named as the hydroxide of the metal in the formula. NaOHsodium hydroxide KOHpotassium hydroxide Ba(OH) 2 barium hydroxide Al(OH) 3 aluminum hydroxide Fe(OH) 3 iron(III) hydroxide
