Alright, phosphoric acid is H3PO4. It is a triprotic acid, meaning it can donate 3 hydrogen ions successively with each reaction (we'll explore more into this as we go) and is a relatively weak acid since its degree of ionisation is not 100% ie. It does NOT disassociate completely when mixed...

Re: Buffer solution question Alright, I'll keep that in mind. Thanks :)

But yeah so just work through those exercises and re-learn complex numbers. Will do. Thanks boiz :)

Too late my friend ;)

Got them both ;) Though do I have to worry about Maxima and minima? I'll probs just do exercises from both of those books. So that's it?

I'll just leave MATH1902 for later, so for MATH1901, what do you think I should practice? (I've become REALLY rusty and I'll probably re-learn concepts in depth/develop some conceptual understanding and etc).

"MATH 1901 or 2"? Both I suppose.

do any of you guise know what topics are built upon in uni? Like I (think) it's just mainly calculus but what else? strong maffs newb

It's too early! Plus junior performance doesn't really indicate much imo, it's kind of a different ball-game in year 11 and 12. Like I did WAYYY better in year 11 maths than year 10 maths, same applied with english. I'm talking about like my very first few assignments where I studied the same...

Up and working now.

Bump.

hehehe really?! (nah i doubt it) dayum gurl ;) make sure to bring da country road bag for authenticity :p

Re: Buffer solution question ...Well this is awk.. Thanks! :)

Yay for USYD ~~~~ (I'll be on my way out nao) ^___^

Re: Buffer solution question .

:(

y = -2x^2 -5x + 3 So factorising, we should get: y = (-2x + 1)(x+3) Let y=0, x = 1/2 and x=-3

Re: Buffer solution question Bump.

re: HSC Chemistry Marathon Archive Alright, thanks for clarifying. Can you tell me what this "somewhere" is? ;) I've been trying to look for practice calculation questions online but I'm not finding many things that are relevant/useful to me.
