Back Titration vs Forward Titration
« on: October 22, 2012, 08:28:59 PM »
Hey,

I was wondering why forward titration are more favourable than back titrations? Just a question I thought of as I did my first back titration in the lab the other day and wondered why we always do forward titrations.

Cheers!

It really all depends on how we can visualize the titration endpoint to determine which we will choose..  I suppose, since back titration is two titrations in a row, you may have doubled your possibility for error.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Yes, that's what I thought too. Because I am doing two titrations I double my chance of random error.

It can be end point detection, it can be kinetics:
