Where we ad to ryt the dif in the reaction if potassium iodide were used instead of potassium chloride...
it's nothin lyk dat. it's jst he sort of makes fun of other ppl's mistakes. plus, he nvr commented on my ans.
Ohkayy...tht took me like ages to understand!Hey
come on
He's only trying to help. He never said you guys are stupider than him or anything like that.
As far as I know chromatography IS right - dissolve it in distilled water, make chromatogram. Melting point may actually bring complications since when heating the water of crystallization will escape, but whatever.
THe original reaction is:
Pb(NO3)2 + 2KCl -> PbCl2 + 2KNO3
So for every one mole of Pb you need 2 moles of KCl
The new reaction with Silver Nitrate is
AgNO3 + KCl -> AgCl + KNO3
Now the mole ratio is one
So now you need half the amount of moles (and thus volume) of KCl to react with the same amount of nitrate.

Who r u takin about the guessing dudek, thnx. sry abt my awkward manner. i jst lost my temper. i apologise!!
i'm kinda short-tempered, so plz 4giv me.
So wats the rite answer ThatReallyReallyWeirdDudeOhkayy...tht took me like ages to understand!
I couldnt come up wid tht during the ppr...however tht makes sense...and nw im tensed!! :/
thats right, ya have to mentioning the same volume etc etc
Yup no wunder it was of 7 marks
how are we supposed to know that? abt the gas given out??For the first question heating the Fe(II)Sulphate, you get SO2, Fe(III)O and SO3(White gas)....I checked online and this seems correct
no, Nawaf!
Wow I wrote that yayyyy
Oh dunno him
Will I?
he posted mny comments in dis thread in da earlier pages.
why would iron turn to oxide? i cant judge but according to what that person wrote abt the gases given off it isnt right, right?
K I went outta pic then
Actually iron oxide this is how sulphates of middle order reactive metals are reduced like the guy said checkout the Internet it's also in my book Prescott gcse chemistry
ummm... wadya mean "den"?
idk
