well i think everyone gets the same solution until its not a different varient . maybe you had some problem in neutralising the HCL like proper ammount of alkali added or it can be something wrong with the solutin lol. who knows any ways its already gone so dont worry abt it . how the prepration for MCQ ?
WELL your test doesnt matter much its just the way you present your data and your observations . just make your tables right and write your observations properly and make your paper look neat and clean . i think thats what matters.
and it doesnt matter what you write first s1 s2 or s3
InshAllah you won't !
may God be with us and we turn out to be right!
hahaaa yeah! still didnt start preparing i have AICT on tuesday :/
YOU DID NOT GET SUCROSE BECAUSE, you did not neutralize the solution properly, we always need to add Na2CO3 or NaOH in EXCESS until bubbling stops...then we add the reagent and test for color....
bro ... did any question involving microscope came?I HOPE it's easy or I'm a goner. :$ Many thanks btw. Best of luck to you for your exams.
I KNOW THAT and i did add it in Excess !!!! Still no sucrose!
i don't see you or anyone else needing medical attention.
i dont have this as my subject . i've got MCQ'S starting from 10 june.
w did you do the graph plan diagram where you had to count the boxes and all .
everyone hopes the same lolAh alright. Hope we get a lenient examiner.
My examiner helped me!! saying starch is hydrolysed!. as when we react starch with the enzyme is breaks therefore starch is hydrolysed!!Guys it appears there been a big mix up, some people had results hydrolysing sucrose, some had results hydrolysing starch :s
Mine personally, was hydrolysis of S1, and it couldnt be wrong because i did it like 3 times >_< wth!
And only one biological molecule could be present with each test-tube, but it could be repeated. e.g s1 and s2 both glucose, s3 starch, etc, but never more then 1 molecule in each.
What do we do now about the mix-up? I really don't think my teacher is going to pay any attention to my request -_-
