Oh really then most of student in my center got a negative answer in (i) - (ii). I know shouldn't be negative but it was. -.-

If at ypur center preparation of solutions was bad, CIE will normally not penalise if everybody has trouble.

Good. What was the answer to the last question? Because I kinda screw up on that

salt contains water of crystalisation

salt contains water of crystalisation

What salt was it?

 

[PrincessLuna]

What salt was it?

I don't know, it never said to identify it.

 

[shahbakht]

I don't know, it never said to identify it.

I know. But I thought it was a sulfate salt.

 

[PrincessLuna]

I know. But I thought it was a sulfate salt.

It doesn't mater what it was, as there are no marks for that.

My mind wasn't at ease but I hope I did Ok.

Before the practical, they told us to go to the toilet and I slipped and fell there . Wasn't hurt but got quite dirty and my socks were drenched. I could not concentrate properly after that.

I slipped again near the testube rack after salt analysis and broke 3 test tubes and spilt some stuff on my question paper. Nothing much as it was mostly colourless. They made me sign something saying that I broke it at the end. What about you guys? Will I lose marks for breaking things?

I was a bit stressed and nervous, but I think I did it ok

i hear u i understand yo

 

[KARLOTTAMAN]

princess luna u sound beaitifull lol

 

[snowbrood]

Nope. Not all. I had time shortage so I really rushed the last question.

What do you mean by no change? Also how was it?

 

[snowbrood]

What do you mean by no change? Also how was it?

no change when we added naoh and nh3 . we all thought one would be barium while the other one would be ammonium

 

[snowbrood]

i prepared so much and now all that hard work is gone thanks to my f centre i wanna die

 

[PrincessLuna]

If you all had the same issue, CIE will give you marks, apart from that how was it?

apart from that i nailed it girl

 

[PrincessLuna]

Lucky you, I'm not sure if I did all calculations right and the last few salt tests with ribbon etc Wasn't really concentrating

well u appearing for first time . when i appeared for first time i was also confused as i had severe tooth ache this time i dont want the history to repeat to itself

 

[snowbrood]

work hard give ur best in p1 and p2 u might end up with an A

Copper Lead and Carbonate ...

I suppose that anions were asked for both the solutions. If one is carbonate, what about the next?

 

[Prasun]

How did you

Same but there one cation and one anion in each test tube which mean 2 cation and 2 anion.. My was copper lead carbonate and sulphate.
Acha what was your average volume used in titration if you can remember? I want to be sure!

How did you come to know that the next anion is Sulphate?!
