Chemistry DONE!!!

guys the question of the soluble salt that was made by titration,the question that asked how to remove the indicator.
in the question did he say that the volume of the acid needed to neutralise the base was NOTED or not?

which varient ?

 

[vishalgodhani]

which varient r u taling about

which varient ?

Variant 1

 

[vishalgodhani]

i m sorry but i have given paper of varient 2

me too .. and it was pretty simple !

 

[vishalgodhani]

me too .. and it was pretty simple !

ya but i was nervous tooo.......

it seems as if variant 1 was harder than variant 2 which is very odd.

 

[m3dchemist]

that's also correct garnesh but i felt magnesium oxide was better

we can use the magnesium mteal to and it will be in excess and then we filter it off ^_^

 

[m3dchemist]

Guys yeah .. What did you write about the pH?
What about the solution of MgCl?
And how do we remove the indicator?

which ariant u guys are talking about 31 or 32

ya but we are safe then its ok...............

Variant 2 was soooo easy
im scared gt will be high as a result

LOL the GT's for chemistry never went above 160/200 for A* so you should expect something more like 150-160/200 which is considered safe.

That is the saddest part.

guys r u sure the gt marks r outta 200?????????????
cuz getting 150-160 in this sub isnt a big deal if its out off 200!!!!!!!!!!!!!
BUT if this is the case then now i m mch more safe

the total marks for all papers are 160 but CIE's grading is from 200. if you would like to calculate your percentage mark then do the following. find the percentage mark of p1 from all papers which is 30% then multiply 30 with your approximate mark in p1 say 38/40 to find the percentage mark of p1 out of all papers then repeat the same procedure with the two other papers. p3 accounts 50%, p6 accounts 20% and p1 accounts 30%

thanks.....................
BTW couldnt we jst calculate our total marks and multiply wth 1.25 as some said it b4r as it shows the same results.......
thanks again n bst of lck for the cuming papers(if any left)

 

[Prachi mansatta]

the paper was more theoretical than practical !
-variant 2

No you can't, since each paper has a different percentage mark from the total subject mark. for example p1 accounts for 30%. also p1 and p6 have the same total marks but they account for different percentage marks, so i wouldn't advice you to use that method because it's inaccurate and unreliable.

Based on the survey above, it is estimated that the mean value for the GT's will be 159/200.
