Relax, nothing like that! Most of it would be repeat!erm.... what is the difference between pattern change and questioning style change? it mean there are no longer fixed question like qualitative analysis and titration in paper 4?
even i dont knw what is pattern change! I'm not in contact with my teacher otherwise would have told you!
So just forget any changing stuff and STUDY! they are not gonna ask anything from physics? so WHY WORRY?

what are you saying confusing everyone about the question change and pattern change??? If there was to be any difference in paper, a specimen paper would have been given! what is ur source about this other than ur teacher?
Please do not post material which may cause other people to die of heart attack as they have the paper the next day!
lol....

if not mentioned, it is concentrated. A long and lengthy discussion has been held before on this same thread, and it was finally proved from the ms that if mentioned only aqueous, NaCl is always taken conc. and btw, only electrolysis of conc. sodium chloride is included in our syllabus!

Aqueous is aqueous. Why are you guys fighting over it being conc. or dilute? :/
Aqueous solution is simply a solution of a substance in water. The solution contains the +ve & -ve ions of the substance dissolved and water (H+ & OH-)
I never troubled myself into thinking whether it would be dilute or not, so I never assumed unless it was mentioned!
