Lol I bs'd it too.

One point I looked at was the volume of the water body as a whole. Chlorination would be a much more effective way of treating the water for microorganisms, than something like reverse osmosis - due to high costs yadda yadda.

Then my 2nd point related to any industrial sites in proximity leaching out toxic wastes such as heavy metals in effluents. precipitation and microfiltration would need 2 be used bla bla.
lol
WOW.

Er, do you think that if you can persuade the marker to look in the way you interpreted the question, you'll still get marks?

Lol so u reckon 0/5 for me?

I also talked about AAS being used to analyse water samples for presence of heavy metal cations... maybe shud get something for that.

P.S. Do u mean WOW, as in I totally didn't answer the question, or the other way?

im pretty sure it didnt say YOUR local catchment... just a catchment
Yeh it didn't say YOUR. But I just went ... The sanitisation process of a water catchment, such as the blah blah catchment for example, depends on its properties. + Sources of contamination for my local Catchment + ways they treat this

Danz, just that your answer does look right. But since I'm not even sure what it really means, I can't confirm that you'll get 5/5 for it. But you haven't answered my question, we'll get marks if we can convince them?

I just know that by mentioning "contaminants", you'll get a mark.

Poly tetra fluoro ethene: I did screw it up. As far as I know that I finally got the right answer but (!) I sort of crossed out like 3 times and ended up writing the results one line below the ...... It's just confusing 'cuz I keep looking at the second column. But it's maths, how further can it go?

the chlorine.
platinum is inert and just transfers the elctrons
h i thought chlorine was the anode, coz it gets oxidised??

cl- loses an electron to become cl gas... oxidation is loss, reduction is gain?

i hope im not confusing with soemthing esle here

I thought it was fairly easy...none of the stuff I didn't know xD The multiple choice were a bit wierd and I bullshitted part of my elective, but I could have written more if there was more time.

Well, I think so. I've read somewhere on this forum, I think cem said that, that she's come across a script where the student has answered/approached the question from a very different angle etc. and then the senior marker decided it was an A-range response.

So I think yeah, if your resonse is logical and valid, then you should be fine.

Then again, I agree the question was worded a little stupidly..

You're studying too much. Relax.

OK, to become a negatively charged ion, an atom needs to gain electron. Gaining = reduced.

So Cl2 is of the cathode.
