The error bars should be set at 1, not .5. This is because you have to account for the .5 error twice when you subtract the two temps.
The actual ratios are as follows:
Bleach:Na2S2O3. 4:1
Bleach:KI. 3:1
Bleach:Na2SO3. 1:1
Also, checked on IB policy and you don't have to write the procedures in past tense...yea!

For the Lab write-up on "experimental results" do we have to draw the graph.....because on the section "processed Data" it mention about graphs also.
Which one do we put the graph under? I was thinking Processed Data but not 100% sure.
hey kat... wouldn't the processed data be the graph that we've been working on on Excel??
Not under the context of "lab info", but where can we find the lab that you wanted us to look over tonight ,(9/4), before we perform it tomorrow? Thanks!
I was wondering where the information about the lab for Friday was as well, I can't seem to find it anywhere...
