    well it depends if same volume used that means ends at same thing, there can't be more than one variable or tell me which year in pastpaper and i will check it :)

    such a frequent question and i m learning it a day b4 the exam...oh my GOD...anyways as usual helped a lot ah its okay i went to the bio exam without with only half the syllabus >_< so we all have our problems..lol oh there is also questions about identification using also chromatography...for...

    it is a very frequent question so you have to know a few things if we want to decribe an experiemnt to seperate colour or dyes you have to say chromatography paper (u have to say the word paper because there are other types of chromatography lost marks because didn't say it once) anyway also...

    well by knowing which reaction was faster..it depends some factors (am gonna say what makes the graph steeper) 1) the concentration of teh gradient if the other reaction had same volume but more conc. then it is steeper 2)surface the area..the larger the surface area the faster, the steeper the...

    ya you could use that or you could even use silver nitrate ( something extra you could add nitric acid to makre sure there are no carbonates) but basically yup oh and for iodine , you can use the same thing but the result will be yellow

    Chemistry doubts..ask here!

    are u sure because i remember when doing graphs and they differ the concentration..the one with less conc..will be less steep but will end at the same volume of the first reaction indicating that the rate will differ but not the product it self :/ nooooo it is less steep and it doesnt join the...

    Chemistry doubts..ask here!

    my teacher always told me don't say the indicator's name because sometimes a certain indictator can't be used with certain reactions..so just say add drops of an indicator and then it will change colour ( don't worry my teacher has over 20 years experience and many students who studied with her...

    Chemistry doubts..ask here!

    when i do it i usually put the alkaline in the conical flask n the acid in the burrete, to avoid confusion u don't have to say which indicator did u put and just simply state that we add the acid from the burrete until the indicator changes its colour...and u note the amount of acid that was...

    hey..this is weird..really weird... ya i had this account on facebook years ago because i wanted an extra friend in pet society so i made an extra account..lol and i added ppl who had ones and anime fans n i guess i added u..lol i didn't know abt igcse back then..lol XD ya i am in jeddah

    ya i got it now..lol but for ur first question..isn't it the same product because concentration affects the rate of the reaction but the volume determines the product..?

    well i would really like to help you and haochen did already but i got myself confused, because it all depends on the question...because i know if we keep the same volume but different conc. the rate will differ but the same product about the second question..i don't really know..i kinda didn't...

    so here is a file that could help you..i didn't do it, i actually found it on a recent forum here..so no credits so i hope it helps ^_^ ( btw i don't really like chemistry but chemist narutogirl sounds cool, lol )
