Edexcel CHEMISTRY DOUBTS!!!!

[~ Miss Relina ~]

but won't it form H₂CO₃ instead of being more dissosiated 

well wait a sec............I figured it out

HCO₃^- has lost OH^- group so considered a  base that's what I think

That's also right
HCO3- is actually CO2 and OH-

I get it now..Thanks

plz who is giong to do unit 5 or for who have already done unit 5

I wanna ask about tose points and whether I really have to know specific practical procedures for them or not

eCarry out the reaction of phenol with bromine water and dilute nitric
acid and use these results to illustrate the activation of the benzene
ring

fDescribe and carry out, where appropriate (using butylamine and
phenylamine), reactions to investigate the typical behaviour of
primary amines. This will be limited to:
i characteristic smell
ii miscibility with water as a result of hydrogen bonding and
the alkaline nature of the resulting solution
iii formation of salts
iv complex ion formation with copper(II) ions
v treatment with ethanoyl chloride and halogenoalkanes, eg
making paracetamol.


I need reply plz don't just ignore me

Relina, i think these specification points relate mostly to the practical qualitative assessement but are likely to be tested in the written paper too so know them well.
Do you have the Edexcel A2 chemistry Revision Guide? See how much u have to know from there.

do u have any papers in JAN

plz one more thing do I have to do an experiment to investigate the miscibility  of amines in water or just undrstand the concept as they ask for describe and carry out

Check it according to the syllabus. But if I am not wrong, you only have to understand the concept well.

that's how my syllabus ask

You do not have to do the experiment. Just learn it.

Thanks Dr.Romeesa-Chan

Thanks Dr.Romeesa-Chan

Most welcome, patient.

Yes, i m having exams this jan.

You do not have to carry out these reactions, only the Home centre candidates have to.

Assalamu Alaikum Mkh,

May I know what is the written practical code number for Chemistry Unit 3 and Unit 6?? I was confused, as there is 6CHO7 and 8CHO3,  6CHO8 and 8CHO6??? Which one?? I want written practical paper not THE PRACTICAL, WHERE I HAVE TO CARRY OUT THE PRACTICAL SKILLS IN THE LAB//

pls i need ur reply asap.

[Romeesa-Chan]

You need not do the practicals. Just learn them.

Only schools provide the lab sessions.
