umm no.. i now get the diprotic, triprotic etc. bit but idk about the degree of dissociation. lets say acetic acid, ionises 1% in solution, and [H+]= 0.1M so pH= -log(0.1x1%) would that be right?

lets say [H+] of phosphoric acid is 2M so pH will be -log[2x3] yup? but if it ionises 10% (making this up btw), then pH= -log(2x3x10%) am i right? please tell me im right.

how do i find pH and [H+] of diprotic or triprotic acids? can someone please go over finding pH and [H+] for me please? thnks

ohh if you could help me with chem? can you tell us the titration process, like making the standard solution, its properties, how to do the titration and the equipment needed? i would appreciate that a lottt. thnks.

already downloaded everything off it. did cssa ones, i will do the others after trials. i only need cssa for now thats why. thanks for your help again.

wtf did people do the cssa chem today?

I said scientists are working on artificial eyes for blind people and made up some implication on it. Is that good enough?

umm i just need the cssa papers for physics and ext.1 dw bout chem now though, its 2morro. i'll just go over my notes for it. so ye thats it. thnks again

hey i was wondering if you have any cssa for chem, physics and ext. 1 maths. i would really appreciate any help. thanks :)

nope :) thank god for that.

wtf! wtf is a bionic eye :s omg im so screwed i only wrote about cataract treatment and use of convex and concave lenses thats 5? marks gone :(

omg already! do we get umat results back before the uac deadline?

did anyone do a 7 marker on eye technology, its implications and future eye treatment options? it was one shit as thing.

sooooo tempted to trust you.

Damn I said record how long it takes for bubbles to form... damn it.

does anyone have 01, 02, 03, 05, 07 and 09 cssa chem? any help will be much appreciated. thanks in advance :)

we didnt have them. i wanted a pedigree chart coz i understand very clearly, we didnt get one.

i didn't talk about transgenic species, i talked about antibiotics, ddt and cloning. the last two i talked about very shortly. was this the assess q. or the evaluate q. though?

too many 5 markers and 7 markers for my liking. MC i thought was hard... harder than the past CSSA ones for sure? ye for communications, 6 marks for reliability and validity. i feel confident coz i have always lost marks for em and i go home look over it and try again, then come test time i...
