CHEMISTRY PAPER 34 On 31st MAY

so we are expecting this reaction to come

so, when timing, do we have to take multiple readings, then average. Or one reading only?

Ok guyz. According to Hassan's picture posted,
sir said 60% chance of rates , 40% chance of titration.
Tyoe iodometric with CuSo4 in google
Also small enthalpy might come if it is rate, but a bigger one might come if it is titration.
Qualitative Analysis Notes : Mn2+ or Al3+ wont be present it seems (not reliable)

what about the one question you knew xD

exactlyyy thats what I was thinking!!

 

[Dukula Jayasinghe]

But CuSO4 will be hard. So most probably, just kinetics question, enthalpy question and the final thing ANALYSIS shit

 

[Dukula Jayasinghe]

OVERALL, where is KI in hassan's list?

 

[DeadbeatCIE]

What is uncertain is whether there is Kmno4 or KI
once which is coming then we are sure of what the hell is coming

if there is starch its ki tbh

if there is starch its ki tbh

yes i am almost certain, the reaction will be the one video i posted previously.

is titration coming?

be prepared. It is possible but unlikely.

practice everything man what if we go in the hall and the reagents are nothing that people described over here?

 

[DeadbeatCIE]

Actually that is quite unlikely

 

[darks]

hahaha that usually never happens : p The confidential instructions are confirmed by multiple teachers. But everyone should be prepared for each type of question, as our reagents can be used in many ways.

I also believed that until I saw what happened to us in physics practical.

So its final then Kinetics and Enthalpy change are most probably coming tomorrow.

This might be what we are looking for

The cations and anions are still missing and this time we could have upto 3

nooo not missing.. Copper/sulfate/carbonate should be in your mind..

Yes the most close to what is coming in our paper..
If similar q. comes in our paper, do we have to take 2( or 3?) time readings with mean? or only one?

3 readings recommended with mean

Here is my final guess
Cation: Cu2+,Unkown
Anion:So4,CO32-

further input would be appreciated

i think, exactly that..But a conclusion can vary for example, sulfate and sulfite both might be written in a conclusion if excess dilute strong acid is added later, or not added. So we must all read the questions carefully and not make mistakes thinking that "Its sulfate! the guess was right!"
