Hi everyone, hope you are well.

I done the above named experiment and I must answer related questions of which I am a bit stuck and would appreciate help.

1) Accounting for errors in titration. How is this done?
2) Estimating the precision to which the burette and pipette can be read and then working out the overall expected error in calculated titres
3)I need to find the literature value of the partition coefficient but as much as I searched I could not find it.
4)Why was water added to the octanol layer before titrating it?
5) why must 2 different indicators for titration of hcl, and acetic acid with naoh 

Any help with regard to these questions would be greatly appreciated

many thanks

Steve

We need the full procedure to comment.

Also, you must show an attempt this is a forum rule.

Re: point 3: Really? I found it in the first hit on google when I searched for logP acetic acid:
