    will titration be on hsc paper?

    Ahh. That's all the graphs are. I can do that

    Winkler method

    Oxygen sensor electrode will do just fine. Just make sure you calibrate it first

    Most common acids + bases

    Wow, that's not to bad. BTW citric acid is 2-hydroxypropane-1,2,3-tricarboxylic acid but I highly doubt you are expected to know that

    Most common acids + bases

    Of the top of my head... Citric acid (C6H8O7) Acetic acid (CH3COOH) Sulfuric acid (H2SO4) Hydrochloric acid (HCl) Phosphoric acid (H3PO4) Nitric acid (HNO3) Carbonic acid (H2CO3) Sodium hydroxide (NaOH) Ammonia (NH3) That's all I can think of that they'd expect you to know. And...

    naming esters/structure of esters

    Nope its ethanol and butanoic acid. Just remember the longer one (acid) becomes the longer one (-oate)

    will titration be on hsc paper?

    Solution of known concentration goes in the burette, and the solution of unknown goes in the conical flask

    Conquering Chemistry-eutrophication

    No the algae consumes the oxygen, causing it to die. It is the dead algae that provides the right conditions for bacteria which release toxins into the water, killing everything

    Molar heat of combustion

    You would, and it is the most amount of energy released that is the most effecient. Answer would be propanol

    Question Hsc 2003 Q24

    A weak base or acid should be used to neutralise any spills as any excess won't be harmful. Sodium hydrogencarbonate is good to use as it can be in powder form (easier to control), and it is amphiprotic and can be used to neutralise acid and base. Then do your equations for behaviour of that...
