Active member

i dont think i can explain that...! Maybe neeha is right..!

Active member

Q4 (b) (ii) is frm ionic equilibria............

Active member

application of what..?

Active member

oh ya!! Q4 is under part 2 secA ...............and that question is from ionic equilibria!!
i jus saw the specimen!!
dat comes as an application of buffer solution in qualitative group analysis of basic radicals!!!

Active member

in fact the answer is that group 2 radicals (like Cu) precipitate as sulphides in the acidic medium
while zinc being in group 4 precipitates only in the presence of a basic medium!!! paper - Chemistry Specimen Paper Discussion Icon_cool

so wen u have a mixture of acidified copper nitrate and acidified zinc nitrate....... copper is precipitated wen H2S is passed ........

Active member

yup neeha's explanation is correct........

Active member
