[ayush jajodia 75]

i got 388

 

[ayush jajodia 75]

ratio i got as 2.5

 

[urvi kapoor]

What was x? Water of cryst...

 

[ayush jajodia 75]

bacl2 xh20

 

[urvi kapoor]

What was the value of x

 

[ICTloverz]

The value had to be found by deviding the mean moles of H2O / Mean mass of BaCl2??? tell me yeS!!!

 

[insomniac]

Wid fe2+ it was Nh4+ n SO4^2-
N da others were chromate lead and carbonate

 

[insomniac]

What was x?
N i messed up last part of titration the relative formula mass i just couldnt get it

 

[mather marshal]

Wid fe2+ it was Nh4+ n SO4^2-
N da others were chromate lead and carbonate

i got the same

 

[Nisha Kolhe]

same here
what about that ratio of bacl2 and h20

1:2 so 2H2O

 

[Nisha Kolhe]

The value had to be found by deviding the mean moles of H2O / Mean mass of BaCl2??? tell me yeS!!!

We know the mean number of mols of water
And we also calculated the mean "mols" of BaCl2 (mean mass of BaCl2/ RFM of BaCl2)
Therefore

For example ,
Mean moles of water = 0.006
Mean moles of BaCl2 = 0.003

BaCl2.xH2O

So we have to find how many moles of water for 1 mol of BaCl2
=> 0.003 mols of Bacl2 - 0.006 mols of water
Hence 1 mole gives 0.006/0.003 = 2

 

[Unreal]

What were FA7 FA8 and FA9??

 

[Ujjwal Basnet]

with fe2+ , i got Nh4+ and so42-

i got a s042- bt dont knw abt the other...but i guess most marks are for observation aren't they?

mine was 0.007 and 0.002 or smthng the ratio was 2.83

 

[Ujjwal Basnet]

was anyone's titre near 23.3 cm3

 

[Nisha Kolhe]

mine was 0.007 and 0.002 or smthng the ratio was 2.83

That's totally fine I was just giving an example

 

[urvi kapoor]

How did you show whether your two results were consistent?.. Second question , last part

 

[Abhi Mevawala]

i did it by findin value of X for both
