  1. What are most buffers made of?
    Conjugate acids and bases
  2. Why do buffers use conjugate pairs?
    Le Chatelier's principle
  3. Find the pH of any acid base pair
    Image Upload
  4. Define equivalence point.
    • Moles of added OH- equals original moles of H+
    • pH of 7
  5. Define endpoint
    When the indicator changes colors.
  6. Define the Qsp of an ionic solute.
    MpXq
    • since the [MpXq] is constant (because it's a solid) you can multiply the Qc by [solid] to get the Qsp
    • Image Upload
    • At equilibrium Qsp=Ksp
  7. What does Ksp tell us?
    The higher the Ksp the more soluble the substance
  8. What is a complex ion?
    A central metal ion covalently bonded to two or more anions or molecules.
  9. What is a ligand?
    The anions or molecules bonded to the central metal ion of a complex ion.
