    Prac on acidic environment

    Well I guess it has got to be a titration then. Or a pH probe investigation. You'll probably have to do an HCl/NaOH titration ~ everyone does. Do you understand the principal of the titration? You could read the the right hand column of the syllabus for ideas.

    Prac on acidic environment

    Would it be so hard to get another one? I mean you've just said were doing a prac on any module... We can explain things, but we can't read your teacher's mind!

    Hsc Chemistry Resource Database

    The movies are cheesy and in placed flawed. Some broken links. I'm glad to see that Board of Studies is more helpful nowadays. You should be careful when riping stuff off from the US. First ionistion enthalpies, for example, are not complete, not correct at standard conditions and the...

    Oxygen And Ozone

    Well, you should be aware of the ozone cycle. UV breaks down (disproportionates) zone to diatomic oxygen and oxygen radical. Oxygen radicals rapidly seek other oxygen radicals to form diatomic oxygen. Ie oxygen radicals are very reactive, but exist. Because of the resonance the bond...

    Titration results

    I can remember wanting to throw up desperately. That purple stuff was vile, and I don't think it mixed with all those free meat pies from the Dean :D

    Forensic Careers

    It would be stupid for a chemistry course not to have analytical chemistry ~ it is easy but you'll get sooo tired of statistics. All results have an associated confidence interval in which the correct answer has to lie, or you get 0. But on the flipside if your interval is too large then you...

    help please

    No it isn't ~ I could crap on about analytical chemistry, but you say you want effects of heavy metals in waterways.

    Variables for pH testing and Temp

    Are you after 'things to measure' or 'sources of error'. When you say pH, do you mean measuring pH or the pH itself. If the former, which method or all? Temperature measurements can and should be corrected for atmospheric temperature, since most of the glass is in contact with the atmospheric...

    question

    amount KOH initially = 0.05*0.1 = 0.005 moles amount KOH after HSO4- = 0.01044 * 0.2127 = 0.00222 moles amount KHSO4 = 0.0028 moles mass KHSO4 = 0.0028 * 136.178 = 0.3785g concentration (w/w) = 0.3785/0.4696 *100 = 80.6%

    Teachers on a tangent/off the subject

    University lecturers are much worse. "yadda yadda ... oh yes I was involved in funny situation, but I don't have time to tell you ... yadda yadda .. read my book (even though it is out of publication) ... yadda yadda ... what does the world have against my giant beard?! ... yadda yadda ... oh...

    half yearly

    And the oxygen Lewis dot diagram is a sham. Oxygen is really a diradical. Did you know they've made O4?!!? It's a red solid. Needs pressures above 200000 atms though :(

    Titration Comp

    You remember professor Hibbert's statistics!! You can't possibly say who has won without confidence intervals ~ the whole thing is a lottery of the capable! :p
