Remmebe concentration li sit ion for predicting e cell
Everything is assumed 1 moldsim-3, if it’s greater EQUILBKRUM shifts, if the electrons used up less negative if more produced makes more newgrife
What. Ames trbsdjtom
This if there is at lest d one ion that has a partially ful d orbital in them
Sn and zn are the only two d block that aren’t bscusde has full and empty, but not partially ful,
Forming 3+ for sc and 2+ for sinc
3 characrerisict oroeoties of transitions elemtnd
They form colours in soltuoj
Can form various oxidation states l
Can act as CALAYSTS
What does colour depend on
The oxidation. State
Fr 3+ green, cr 6+ iange
Got reduced as it is an xoidifn agent
a remmebe when do the colours show?
Only in awueousnform

BENEFITS OF CALAYST
Reduced energy usage
Prevents toxicity from TRANSITION METALS
When 4
If chlorine ions used then it will be tetrahedral as they ar e it looks
If platinum gold etc then square planar
Cis trans octahedral
Cis long as two are next ti each other, must be two standkone and when opposite trans
First all when we do predication with ammonia what happens
Bun the whole ammonia off it just becomes cu + Oh auto make the predicate lit just show thst
Colour changes ligand sub
Hexa copper
Hexa cooler = pale blue
Add ammonia forms blue lrecioste if cipper hdyrocide l
Sdd excess ammonia and ligand sun happens ti form dark blue! Copper 4 ammonia 2 water
(Dissolves )
Add drop wise
Hexa copper and chlorine
Forms a reversible reaction, add chlorine copper 4 chlorine 2- , and thus js yellow
So pale blue to yellow, it ermdisye green
CR hexa 3 + + ammonia
INITAL colour = VIOLET
Add nh3 orecuoste which is grey green
Continue to add nh3
Becomes Cr nh3 6 and PURPLE COLOUR
Haemoglobin
Problem with carbon monoxide?
Each hamelglobin made from 4 conjugate proteins with iron ion in them, these bind to oxygen that carried to make oxyharbigkogijn, then drops
Also binds with carbon dioxide to carry back timounhe
2) problem with Cabrini mini de is that this binds much more sting then oxygen so finitnrocued soon ebeytbging filled with this + irreversible sonfewth
Remmebe Arole if HAEMOGLOBIN FOR BRETSHIGN IN AND OUT
Breath I carry oxygen out CARBIN dioxide
