pKb of amines
« on: December 10, 2016, 04:44:21 AM »
I am conducting an experiment on trends of pKb of amines
I am having trouble to decide what will be the controlled variable for my experiment:

Methodology:
Titration with a pH meter and indicator.and Using differentiation to get equivalence point.

I don't recognize your terminology.  Or at least, don't see how it fits in the overall scheme.  At any rate:  could you define for us what a controlled and uncontrolled variable would be in general, and list the variables your actual methodology has?

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

It sounds like he wants a standard to compare the other amines to? no?  Like if a list of amines had pkb's of 7, 7.5, 8.2, 9, 11, and 13 (not actual pkb's btw) you want one around 10 to compare all these to? I may be totally wrong and sound like an idiot but maybe not and I cleared something up :P
