  1. Complexometry

  2. Metal-Chelate Complexes

  3. Complexometry Metal-Chelate Complexes

  4. C: unidentatni ligand B: bidentatni ligand A: tetradentatni ligand

  5. EDTA: Acid-Base properties K1=1.02x10-2 K2=2.14x10-3 K3=6.92x10-7 K4=5.5x10-11

  6. Y-4 = [Y-4] [H6y+2]+[H5Y+]+[H4Y]+[H3Y-]+[H2Y-2]+ [HY-3]+[Y-4] Y-4 = [Y-4] [EDTA]

  7. غلظت مولار Y4-را در محلول M EDTA 02/0 که تا pH برابر 0/10 بافری شده است را محاسبه کنید.

  8. [Y4-]=α4CT=(0.35)(0.02) = 7.0x10-3 M

  9. K1=1.02x10-2 K2=2.14x10-3 K3=6.92x10-7 K4=5.5x10-11
