Bonds between the 2 chelating ligands in the NiDMG complex are what type????...(1)..........////
What parts of the two ligans is the bond between???? (2) - DMG H bonds between the H of the OH on one DMG ligand and the O on the second DMG ligand
- What is the formula that results in the NiDMG complex?
- 2HDMG + ni 2+ --> Ni (DMG) 2 + 2H+
- Why is NiDMG needed to be filtered right after preciptation?
- DMG insouble in water.. and added to an aq slution of NI sampe.. excess DMG co preciptates with NiDMG2 complex
- What drives the NiDMG reaction in the forwared direction?
- Lechatliers principle.... remove H+ by making soltion alkaline... initional precip in slightly acidic just so preciptae is pure then after precipt cmpleted made slightly alkaline
- zero spectro by
- distilled water
- Filter switch at
- 600 nm
- Spectrum of nickel II nitrate
- set spec to 500 nm... adjust to 510....
- Absorbance =
- 2-log(transmittance_
- Set wavelength first to
- 500 nm and then aduct to 51-
- Acetic acid/ acetate buffer ensures that
- nickel II doesnt praceipate as OH when ammonia added
