Well the best advice available is to just follow the instructions really .
Cos they explain everything really well.
Also read up on your existing reports, eg. calculations and all that.
Also when your doing salt analysis, always look at the Salt Analysis note at the end of the paper. And try to rule out as many ions that you can
Good Luck !

cause if incase there isnt... what could there be instead?...:-\ enthalpy stuff like heats of neutralisation?
and theres the cations and anions identification yeah?

ooh. good question... we havent really done anything other than titrations in school.  :-\

and i guess for the tests... they wouldnt give you ones that arnt there.
but you might need to know what you're supposed to add to neutralise a solution - like whether to use nitic acid or HCL?? and remember formulas maybe??... and how to differentiate between ones that give similar results. but i think something about Al and Pb is given on the sheet too.
