My teacher said that there are 4 topics which are presented in 3 questions. Those are: rate of reaction, enthalpy change, salt analysis, and titration. She always told us in laboratory that "please be attention, because i've set these as similar as the exam". Yeah she just said just similar. But i don't know if it is the same or not.

Stop freaking out everyone..inashallah it will be good..don't rely on what the lab assistants say because my school is a centre..and our Sir and lab people keep telling us that the CIE people confuse tham too by putting in extra chemicals that might be of no use..just to put people off the track especially these latest years!! Good Luck!

titration question is going to be that of thiosulphate with iodine using starch as indicator, heat question is going to be aeasy, add ammonium cholride in water and you ll have to calculate temperature drop.

what I have been told is that for the titration, we will have to mix sulpheric acid and ammonia together and then titre KMnO4, the trick is that the colour change happens twice, once from colourless to green then from green to brown. I am 100% sure this is the practical 33.
for cations and anions, focus on carbonates, Iodide, Bromide, Chloride, Nitrate and Nitrite, Sulphate, Copper II, Lead II.
Anyone can upload a list of calculations that we can use?
