Q

Remmebe concentration li sit ion for predicting e cell

A

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

Q

What. Ames trbsdjtom

A

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

Q

Colour changes ligand sub
Hexa copper

A

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

Q

Hexa copper and chlorine

A

Forms a reversible reaction, add chlorine copper 4 chlorine 2- , and thus js yellow

So pale blue to yellow, it ermdisye green

Q

CR hexa 3 + + ammonia

A

INITAL colour = VIOLET

Add nh3 orecuoste which is grey green
Continue to add nh3

Becomes Cr nh3 6 and PURPLE COLOUR

Q

Haemoglobin

Problem with carbon monoxide?

A

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

Q

Remmebe fir thr cioler snd chop,opine AMMONIA NOT ADDED

what’s added this time

A

This time COCNENTRSTED HCL IS ADDED IN OLADE IF AMMNIA TO ORIFER THR CL- IONS

17
Q

What is a predication resfiotn

A

When two anions soktuojs come to make a solid

Here we gonna do this by RESCTION trans ion Keemun ions with SODIUM HYDROIDE IR AMMONIA Z, BITH SAME THING

18
Q

Prefisptiok for Mn2+ and cr 3+

A

Pale pink light brown

Cr3+ violet then grey green then dissolved in EXCESS NAOH OR AMMONIA to form dark green hexa chromium

19
Q

I read reactions and colours

MNo4 to Mn with iron

A

This is purple to copurleee, and first sign of pale pink stop

20
Q

Fe 3+ to fe 2+ reduced so 2I- toI2 oxidised

A

Fe 3+ yellow bro,Ed’s pale green
However browm fro, idoidne shown too

21
Q

Cr2072-

A

Orange ti green

22
Q

REDOX REACTION OF CU2+ TO CU+ WITH IODINE AND COLOURS

A

Cu2+ reduced to cu+
2I- licked to iodine

But make 4 I - and this makes cuI too which is a WHITE PREFIOSORE

And I2 is Brianna

So pale blue becomes white precipitate snd brown

23
Q

Dispeootinwtion if copper, what colours are copper SOLID easy and copperuskfsge

A

Any copper compound ish aqueous sis blue

Copper solid brown

Cooed idiodie is white

24
Q

Hard colours ti remmebe

A

So copper iodide white
Copper brown
Violet cr3 + grey green dark green

25
Q

Quaktiive tedts

A

Cwbrinste = nitrified acid effervescence

Sufkste = barium nitrate barium sukfate white orefispt e

Halide ions = silver nitrate and milk cream butter tinderernine

26
Q

How to confide silver halide test

A

Solubility DECREASEs lower you go

Ckbkrine will be soluble in conc
Beijing only cinc not dilute
Iodine won’t be in conc either IMSOLUBLE

27
Q

R,ember caviars

Why must order be csbrinste suffered and then silver

A

Do the silver one last, if do first and there are carbonates and sukfated and not silver, it will produce whitenorefiosted anyways

SILVER PRODUCES WHITE PRECIPATED A

AND THEN barium produced one with csbrinste too so must be done second

Doing csbrinste one first wedge of mind as you know for sure nothing else produced bubbled
