I think there was white ppt and soluble ! though I wrote no reactionwas there any reaction between fB6 and fB7?
neither did I ! .. I did twicebut i did this reaction like 3 times....i got no reaction
btw what were the concentrations of NaOH! ??
in first question I found it as 1.77 I guess ! and the second question I fount 0.166 mol/dm3
in Q1 my concentration was 1.95 and in Q2 it was 1.92.btw what were the concentrations of NaOH! ??
in first question I found it as 1.77 I guess ! and the second question I fount 0.166 mol/dm3
Ohh dude my bad I am sooo sorry ! the reaction I am talking bout is fb5 and fb7 sorry man ! the other one was no reaction !!!r u sure it was supposed to give a white soluble ppt???
and do u hv any idea abt the expected GT?
how can the second one be 1.92?in Q1 my concentration was 1.95 and in Q2 it was 1.92.
the solution for which you were to find the concentration in both questions was the same so its concentration was supposed to be the same too.how can the second one be 1.92?
what I did was ! (moles/((30-whatever I got from graph)/1000))
what did u do ?
Ohh dude my bad I am sooo sorry ! the reaction I am talking bout is fb5 and fb7 sorry man ! the other one was no reaction !!!
I was soo happy after the exam I even forgot to ask him about the GT
dude exactly what I thought ! but the calculations never got me there ! :/the solution for which you were to find the concentration in both questions was the same so its concentration was supposed to be the same too.
I did 2,4-DNPH and Na(metal) !!Can anyone tell me about the answer to the last part where they asked about the identification of some organic compounds.
in Q1 my concentration was 1.95 and in Q2 it was 1.92.
I did 2,4-DNPH and Na(metal) !!
what did you get?what was ur titration reading.....though it varies frm center to center
exactly ! but 2,4-DNPH only react with ethanoic acid and aldehyde! so if both reactions occur then its ethanoic acid other wise its ethanol if only Na worksbut wouldnt both ethanol and ethanoic acid react with Na metal ???
