39Kuch toh jala...zaroori thodi hai ungliyan hi jalenge :P
For CBSE physics board practicals,we are required to do 1 experiment and 2 activities. there do we need to perform them and show the settings to the external? also in chemistry practicals for detection of the inorganic and the organic samples,do we need to show the final precipitate of the group tests or analusis of ppt of group test? please reply!

13Don't try tht again atgs,,,now the handkerchief aint there to protect ur fingers... [144]
1no i'm not kidding guys,some students in another section tried to prepare aqua regia in the lab and a kind of mishap happened,there was a lot of talk about that in school!
1And another thing,i hope we dont need to prepare the solution say 250 ml M/10 of a particular solution.that will be given i presume?
1and avik,if i am asked to do that circuit then i will be in deep waters![2][2][2]
1@akara yes bro there is a difference of life span between ions and radicals!!
13Chalo, meraa chem. toh ho gayaa (with jhakaas viva..!)...physics is left.[1]
@arka...yeah we got "prepare..." but the solution was given. Only thing v had to calculate & write the weight of mohr's salt tht wud be needed to dissolve in tht particular volume fr tht particular concentration.
Aur circuit ke liye ghabra mat, bas sabko parallel combination mein lagaa denaa, ho jayegaa.
39Mera bhi chem mast gaya hai...external mast banda tha. Have never given a more perfect chem prac in my life.
1thanks avik 4 the tip on househlod circuit.
heard from students of another school that no one checked the activities!
wud b good if the same is with us!
13Oye arka, good news...no-one checked out our activities.
Waise, my physics was rather good.
Only thing the external was a "3idiots" type one ; asking Definitions & Terminology .
(He asked me the "Definition" of a "Prism"(..!!! ), followed by the "Definition" of TIR, Refractive index and "the phenomena of Polarisation"...he!he!)
How many of u are done with all ur board pracs ?
49hah ha...my fingers are intact.....very intact.....[3][3]
u must be careful just...nothing else.....[3]
bt ek prob hai...=mera handkerchief jal gaya...
1guess wat...in my chem viva, the external asked me to prove x0=1 for all x!!!
1ME TOO........PHYSICS WAS BEST VIVAS I EVER GAVE..........EXAMINER WAS SURPRISED WITH EXPLANATIONS!! :)
1MY CHEM VIVA WAS WORST ONE OF MY LIFE!!!!!!EXTERNAL NE POORA BIOLOGY POOCH MARAA~~~~~~~~~~~~~ :(
1Physics practicals over today,was superb.
answered all the viva ques correctly and got the easier expt and activities[1][1].external didnt check the progress of expt and activities![1]
was taking pressure without any reason.viva is the only thing perhaps that creates the tension,expt and activities are being well discussed by all[4]
got chem 2moro.
shreyan what if x=0???[4]
13@arka.... good luck buddy...yeh bhi phod ke aana.
@shreyan... u shud have reminded the external tht it was a chem. prac. not mathematics, maybe he had forgotten, short-term memory loss....lol
@bond... chod yaar, 28-29 se kam kisi haalat mein nahi milenge kisi prac. mein.
1At last my board prac.... also over
hoping for the best :)
all the very best 2 all [1]
1thanks avik.
awesome chem practicals too![1][1][1]
external was lenient,answered all viva ques correctly and the expts were well discussed and copied down amongst us.
Finally they are all over!
And surely three of the best tests i have given in my life[1][1][1]
13[1] Yeh, big hurdles crossed brilliantly in the end...khaaskar physics was my most dreaded.
AAL IZ WELL now [4]....!!
1no not till a very strict external comes...........bt only in physics.............chem me you may be asked to perform the test by group testsor ppt method.....................even if u dnt perform the test u mst remember the reagents & procedure
1BEST OF LUCK TO BOTH OF U..........DHYAN SE EXAM DENA...........MY PRACTICALS R OVER..........YA HO!!!!!
13Me too having queries...
Chromatography se viva toh nahi poochte ?
n How much possibility of a Ni/Co salt ?
29they ask for the confirmatory test mainly....that depends on the teacher..sometimes the teacher is busy taking viva..so they do not bother the students doing practical...
i dont think they will ask viva from chromatography...
the possibility of a Ni/Co salt is very less..mainly they give salts having alkali or alkaline cations which can be easily detected by flame test...btw for Ni u may use dimethyl glyoxime..it gives rep ppt...
13yeah thnx, relying on DMG only ...heat karne par mera sab ud jaata hai :D
