The TDS one!
Site C has higher conc of TDS cuz:
Soil erosion: so... fertiliser, nitrogen compounds in water
Located near road: pollutants of incomplete combustion from cars (CO, C(soot))
AND Path of water flow: Water could have flowed over limestone (for example) and picked up carbonate on the way.

idk...but thats what i said

for that one mg/l i think equals to ppm and then divide by 1000 for ppb
ppb is 1mg/1000KG so that means 1PPM=1000PPB and btw there were no pracs in the industrial option right?

Shit. I divided by 1000 for the ppb. That's another mark gone. I though i was gonna get 85/100 and then I see I make more and more errors, and now ill probably get like 76.
I should just drop out of life.
Dude calm down, Others probably made the same mistake too

Please people who did industrial, what is the answer to the equilibrium constant? i got 300 something
and also what did u guys get for the concentration of the weak acid to get the same ph as the strong acid question.. i think it was nitric acid and some other...

you dont want to know.............. :eek:

We did Chem Monitoring first, then Production and now Industrial
Acidic is after trials -.-
....yep :/
Woah! You're doing acidic last?!?! That module is the most heaviest one with the most equations and content to remember... Good luck.
