Chemistry Practical Paper 34

[RJ72NL]

Hey guys! On October 25 we have the 9701/34/O/N/2017 exam! Please would everyone let me and everyone know about what will be coming for this exam! Thank you!

 

[Bishnu Dev]

i also need this

 

[RJ72NL]

Anyone???

hi i'm doing the exam too. so anyhelp would be great. But anyways theres always a titration question and always a qualitative analysis. from that itself you get 75% of paper anyways. the other 25% marks sometimes come from a third question or is implemented to the aforementioned two.

Just hope that someone would provide a bit information about salt test.

 

[Astralgod]

salt test is easy they give a paper of the colour changes and everything just correlate your colour changes with the paper.

i'm more worried about chem A2 paper tomorrow! :-(((cry:

You're taking full A-Levels Chemistry? Great! How is it going?

 

[Astralgod]

well, i had it today needless to say it was horrible paper looked easy AF but it's my fault for not studying.

 

[RJ72NL]

Hey...got any tips for us?

 

[mi1111]

Any tips for chemistry practical?

 

[Astralgod]

Be prepared for titration questions and brush up on your calculation skills for moles.
Enthalpy questions aren't out of the norm so memorise Q=mC^T(delta/change inT)
cation/anion analysis is given in a separate booklet so check whether your results match with them.
Know how to use and write ionic equations.

what were the ions guys?

 

[Astralgod]

what were the ions guys?

For FB 3,4,5,6 question: i got Mg 2+ and for the anion i didnt have much time so i guessed for NO3.

 

[Hasan.]

Cation : I got Mg²+. Few of my friends got Ca²+
Anion : Not sure but i got SO4²-. Another one i don't remember.

 

[Bishnu Dev]

what about the anion that they said is same in FA3 and FA4?

 

[Hasan.]

I don't remember. But my mates were talking about Br- and SO3²-. What were your anions and cation?

 

[Astralgod]

Cant be br cuz i did a silver test. So so3 and So2 was also out of the question it had to be something of No2 or NO3, i eliminated others but i couldnt heat and use litmus papers so i took a guess at NO3... As for cation when i put naoh it was insoluble , excess also same result hence Mg 2+.

 

[Hasan.]

How much mark for one anion test, observation and results?

 

[Astralgod]

Not sure possiblynone.
