6.1

  1. 1. Acids & Bases
  2. 2. Acids <ul><li>contain hydrogen </li></ul><ul><li>are electrolytes </li></ul><ul><li>turn blue litmus paper red </li></ul><ul><li>neutralize bases </li></ul><ul><li>taste sour </li></ul><ul><li>solutions react with active metal (Fe/Zn) to produce H 2(g) </li></ul><ul><li>react with carbonates to produce CO 2(g) </li></ul>
  3. 3. Acids (conceptual) <ul><li>Arrhenius definition: acids are substances that provide a hydrogen ion in water. </li></ul><ul><li>HCl (g) ↔ H + (aq) + Cl - (aq) </li></ul><ul><li>CH 3 COOH (aq) ↔ H + (aq) + CH 3 COO - (aq) </li></ul>
  4. 4. Bases <ul><li>are electrolytes </li></ul><ul><li>turn red litmus paper blue </li></ul><ul><li>neutralize acids </li></ul><ul><li>contain hydroxide </li></ul><ul><li>taste bitter </li></ul><ul><li>feel soapy </li></ul>
  5. 5. Bases (conceptual) <ul><li>Arrhenius definition: bases are substances that provide a hydroxide ion in water. </li></ul><ul><li>NaOH (s) ↔ Na + (aq) + OH - (aq) </li></ul><ul><li>Mg(OH) 2(s) ↔ Mg 2+ (aq) + 2 OH - (aq) </li></ul>
  6. 7. In any solution <ul><li>The product of [ H + ] and [OH - ] must be 1.0 x 10 -14 </li></ul>Autoionization of Water
