Why??
They already give the chart for identifying both ions at the back of exam paper.
I think all u gotta do is copy the exact wording from that chart into observation!
Which exam board u guys doin?? If its CIE then are u takin paper 33s on 29 oct?

hydrogen peroxide - gets decomposed fast. like really fast in hot climate- schools can't store it carefully
so turns to water in a jiffy...and wat good is water in practicals but for drinkin!

mayb there won't b any sodium thiosulfate this time! :P

man i hope not 3 questions   =(
i think there will b just 2
cos every session in a year has 3questions in either may or nov but not both. its a pattern

Since m09 had 3questions...prob. n09 will hav 2questions.

check out: http://www.knockhardy.org.uk/sci.htm
look for notes; error & measurement , mole calc. and some other rate rxn stuff

i don't think rate of rxn will cum this tym...mayb somethin on enthalpy
look @ the booklet in https://studentforums.biz/index.php/topic,4454.0.html
the last pages help

i'm afraid the the format may somehow change..
just like for my bio practicals, every year they have the same questions like asking for the errors, micrometry and blax3 but this time its completely different!!!
and they used to have 2 questions only but then this paper have 3!!  :o
so i really hope they don't change the format for chem prac  :-\
