Week 9

2017: Tuesday 28. of February at 8.15 - 10, and Thursday 2. of March at 10.15 - 17 in 28B.0-5 and ( in the afternoon) in the PC-lab

You are recommended to produce a physical octahedron from paper or cartboard. If you do so, better make two when you want to compare two isomers. You may also fold one if you understand Danish

We run through the last isomerism problems:
Sketch the possible isomers of the octahedral [MA₂B₂CD]
M(A-B)₃ isomerism ?
M(A-B)₂X₂ isomerism ?

Stability constants: "Inorganic Chemistry" Chapter 7, sect. 11-13
"Notes: Symbols in coordination equilibria.
and Lecture Notes for week 9
(include statistical reasons for relative values of consecutive constants)
Case study 1; Q 1,2,3
Also find on Moodle, Section: Problems for Inorganic chemistry: Determination of stability constants -a simple example

The program Thursday will include:
- coloured compounds
- corresponding solutions
- statistical considerations
- Consider the stability data for the Cd²⁺ - ammonia system : Find the maximum predicted values of logK₂, n = 2,3,4 assuming that N is 4 and assuming that N is 6.
- Case study 1 Q6: find lower limit to K₁
- Selectivity? (IC 5 Selectivity)

The PC-assignment in the afternoon takes place Thursday in the "PC-lab" - lokale 4, 27.2 . The assignment demonstrates how to use and benefit from the "Stability Constants Database" SCDbase , which supplies with convenient facilities to visualise speciation in coordination equilibria.
