    This is a website that i thought u may benefit from for this wednesday...
    4 the flame tests, precipitation..and all that...
    http://www.freezeray.com/flashFiles/identifyingSalts.htm
    4 rates of reaction...
    http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/chemreac/rates.shtml
    4 all the quantitave chemistry...
    http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/chemcalc/chemcalcact.shtml
    4 all the information u need 2 knoe bout gases...
    http://www.bbc.co.uk/schools/gcsebitesize/science/edexcel/chemicalreactions/preparinggasesact.shtml
    ===> SUMMARY...that works more as a check list...
    Summary
    You should know that:
    -there is a series of tests that help us to analyse substances
    -in inorganic chemistry these tests help us to fi nd which positive ions (metals) and negative ions are present in an ionic compound
    -there is also a series of tests for gases such as hydrogen, oxygen, etc.
    -these analytical ideas can also be applied in organic chemistry
    -quantitative experiments, such as titrations, which tell us how much of a substance we have (not just which substance we have),
    can be carried out
    -in carrying out experiments it is important to control the situation so that not too many conditions are changing at once
    -when reporting on experiments it is important to be able to present the results clearly; possibly in a table or by plotting a graph
    -this develops into the ideas of a fair test and a controlled experiment – ideas central to any experimental investigation
    -the scientifi c method is based in part on these ideas, so that any hypothesis can be properly tested.
