Presentation Transcript

  1. 6.6 TYPES OF CHEMICAL REACTIONS Single Displacement & Double Displacement

  2. SINGLE DISPLACEMENT REACTIONS • A reaction in which one element displaces or replaces another element in a compound • A cation (+ve) will always replace a cation • An anion (-ve) will always replace an anion

  3. In General ……..

  4. General & Specific Single Displacement

  5. Metal Activity Series • A more reactive element will replace a less reactive element • The reactivity of a metal will determine if a displacement reaction will occur (single)

  6. DOUBLE DISPLACEMENT REACTIONS • Occur when 2 elements in different compounds displace each other (trade places) • Many of these reaction occur between 2 ionic compounds in solution • Often a precipitate is formed (tiny specks of solid material in the solution)

  7. In General……

  8. General & Specific Double Displacement

  9. Homework: • pg243 #1-8
