AS Chemistry PRACTICAL 33

[sufyanalizaib]

what was the titre value ?

no it was zinc

was around 32 to 33.......well what was ur Element at the last part of titration ?

 

[stella jazz]

We had the same i got zinc carbonate bromide nitrate and sulphate for final stiff
And naoh instead of na2co3 but this paper my paper went horrible man very very bad
We had like titration problems and some people were getting magnesium :/
May god help us :'(

the rest is the same....but i wrote nitrite not nitrate

 

[Mayedah]

If anyone got there molar calculation right and the metal as Na can they tell me how did they do it ( inbox )

 

[songjihyo]

What was your Ar for M in the second question? and the element you got for it? i got some transition element with 44 for the Ar..

Okay, my practicle went HORRRRIBLE! I'm appearing for chem AS and ALevel both! I've had P2, P5 and p3 so far and still have two papers left!
Now the problem is, my P2 and P5 went realllyy well! But P3 just couldn't have been worse! What now? :"(
I really want my ALevels to end this session. No way I'm appearing again! Do you think I can make up for the practical if the rest of my papers go well ...?

yah ... bdw weightage of practicals is quite low and also grade threshold always remains low for practicals..

 

[ash369]

Ahh Thankyou sooo much! I'm quite relieved! JazakAllah!

Hey Guyz
in question no.1 where in the table you have to take two readings of your own choice of volume, i forgot that part
how many marks will i loose ?
and what was the enthalpy change ?

 

[CIE xams]

any gueSSES FOR CHEM PAPER 34????????? PLS MSG ME OR POST IT HERE!

 

[h4rriet]

It was nitrite as far as i know.

I wrote nitrite too. There were bubbles of gas with dilute HCl.

 

[Cesar_malik]

We

I wrote nitrite too. There were bubbles of gas with dilute HCl.

had no reaction but if it was nitrite brown gas would hav been there

 

[nightmaressana]

Brown gas was released with hcl in mine.

 

[ahmed abdulla]

Q.1. Hcl titration with naoh or Na2CO3.

Q.2. Enthalpy.
Temp change vs addition of volume of acid.
Gragh nd mcdt calculations.

Q.3.
Salt.
Zn, carbonate, bromide, nitrite

this is wat i got for 33.....

can u plz get for paper 34 bio and chem ....+phy 33 ??

 

[falcon678]

yeah man m trying...lets hope i get it....

 

[ahmed abdulla]
