Chemistry paper 33 how was it?

[Alice123]

there was every slightest hint in the question it was Na.... didnt u ppl notice the last part of question 2???

 

[Alice123]

no ones sure many got different values

A star (Mr BUTTT) we got that wrong!!! it was Na

well many got it wrong it depends on ur titre values if your titre values are reasonable then you get marks

what hint?

 

[A star]

GT expected by acording to y centre saying that will be around 22 to 23 so any one getting around 27 will get full

 

[Alice123]

Basically the same reagents were made to react in Qs 1 n Q2, they asked which gave betr results..... i dnt exactly remember the qs, bt im kinda sure it will be Na

i think so, coz i checked my calculations thrice

i spent one hour on that question so i am pretty sure i asked many people they said nitrogen then they said they wrote potassium now every one is saying Na. . any way low GT so no worry

is this for the last test where they just add Hcl to FA6 and Fa7? cause i remember 1st one for FA6 when you add Naoh with Al foil red litmus turns blue and ammonia is given off and for FA7 No change is seen then Hcl is added where in FA6 a brown gas appears confirming its Nitrite

I wrote the same, exactly and was no change actually observed with FA7 when Naoh + Al foil was added? Ohh Wasnt it add BaCl2 first and white precipitates formed and then you add HCL to those precipitates? The ones in FA6 dissolved in HCl while those in Fa7 did not confirming that it was a sulphate? That's how I did it because I remember it telling us to first add BaCl2 and then to the add HCl to the mixture :S Tell me if I'm wrong.

what about the highest temperature? i got 27

Was the question after table was to find the maximum temperature or the maximum temperature change# Q1? :S

Honestly i don't even remember what i wrote ahahaha

Maximum temperature, and the maximum temperature change was for the calculation part were i totally messed it up

 

[Malik777]

I used Maximum Temperature instead and Volume of Fa2 for max temp in that question Would there b any ecf for next two parts? :/

yup

the paper was good. i did well . the M was Na2CO3

Lol. I got Sulphur, knew it was wrong but had no time :/

Damn, why ain't I forgetting?

 

[Malik777]

Ho

yup

pe so but I heard ecf is very rare in practicals? :S

they give it dont worry

 

[HunzaZ]

they give it dont worry

How can you be so sure? I believe its A'levels so they don't ? :S
