    I. Properties of Acids & Bases
    A. Properties of Acids 
      1. Aqueous solutions have a sour taste 
      2. Acids change the color of acid-base indicators 
      3. Some acids react with active metals to release 
          hydrogen
                    2  4          4       2
            Zn(s) + H SO (aq)  ZnSO (aq) + H (g) 
      4. Acids react with bases to produce salts and water 
                                            2
            HCl(aq) + NaOH(aq)  NaCl(aq) + H O(l) 
      5. Acids conduct electric current 
  B. Properties of Bases 
   1. Aqueous solutions of bases have a bitter taste 
   2. Bases change the color of acid-base indicators
   3. Dilute aqueous solutions of bases feel slippery
   4. Bases react with acids to produce salts and water
   5. Bases conduct electric current 
      II.   Arrhenius Acids and Bases - Svante 
            Arrhenius, Swedish chemist (1859-1927) 
          A. Arrhenius Acid – A chemical compound that 
               increases the concentration of hydrogen ions, H+, 
               in aqueous solution 
                               +         -
                           [H ] > [OH]
          B. Arrhenius Base – A substance that increases 
               the concentration of hydroxide ions, OH-, in 
               aqueous solution 
                               +         -
                           [H ] < [OH]
    C. Aqueous Solutions of Acids
      1. Acids are molecular compounds that ionize in 
         solution 
                         +     - 
         HNO + H O  H O + NO
             3   2     3       3
                         +       - 
         HSO + H O  H O + HSO
          2  4   2     3        4
                       +    - 
         HO + HCl  H O + Cl
          2          3
      D. Strength of Acids
          1. Strong acids ionize completely in solution
          2. Weak acids ionize only slightly and are weak 
               electrolytes 
                Strong Acids                  Weak Acids
                HSO                           HSO -
                 2  4                             4
