But there is suffering in life, and there are defeats. No one can avoid them. But it's better to lose some of the battles in the struggles for your dreams than to be defeated without ever knowing what you're fighting for.

#4 Posted 6:15pm 19-03-10 Re: matching......Eureka 2 = c...that is NESSLER's REAGENT, used in qualitative analysis of zero group which contains ammonium ion. On reaction of Nessler's reagent with ammonium ion, it gives IODIDE OF MILLON'S BASE, which is H[ss]2[/ss]N.HgO.HgI
Self belief is such a peculiar thing. As long as you have it, nothing can stop you, you feel invulnerable. But once it's gone, nothing can bring you up from the "I'm-useless" state you end up in. |

#9 Posted 9:46pm 19-03-10 Re: matching......SO[ss]2[/ss]Cl[ss]2[/ss] is paramagnetic. S is in +6 state, and in this oxidation state group 16 elements have 6 unpaired electrons divided into 3s, 3p and 3d orbitals(all having same spin by Hund's rule). Only oxygen doesn't exhibit this trend in positive ox states(as it doesn't have d-orbitals). [This concept is from p-block elements] EDIT : Wikipedia has described the compound as a [b]colourless[/b] liquid. This means it is diamagnetic, the 6 electrons for S[p]6+[/p] get paired up in bonding with O and Cl. Made a mistake earlier. So its diamagnetic.

#11 Posted 11:53pm 19-03-10 Re: matching......@prirtish... NH4+ testing not iin syllabus naa ?? |
|
#12 Posted 0:21pm 20-03-10 Re: matching......@eure: you cant guarantee anything in inorganic P-block is there, NH3 is there.. so there is no reason for excluding NH4+ also..
IIT has walked to me ... off to IIT K |

#13 Posted 4:36pm 20-03-10 Re: matching......@asish.. check syll dude....it contains list of cations and anions |
|
#14 Posted 6:31pm 20-03-10 Re: matching......@eure: if i remember correctly there was a question regarding Nessler's reagent in the last 3 yrs. (perhaps in a passage) So you can say nothing Even Fe2+ (or Fe 3+) is not mentioned in that list.. But u have to know them

#16 Posted 6:55pm 20-03-10 Re: matching......Ya eureka What's the ans finally Am I correct ??????
