Mark As Inappropriate
I hope you're staying healthy during this new normal.
I had a rather elementary question about titration. When I perform a titration at work, my boss (a chemical engineer himself) insists on waiting just 10 seconds for the color to change back. However, in school I remember learning that the titration is over when the color change is permanent (about 30 seconds).
I know that reality and theory are often disconnected, but can anyone tell me why my boss has given this directive? He insists it will only have a difference of 1 or 2 drops of the titrant.
I think it's worth mentioning that the system that dispenses the solution I titrate does not exactly function flawlessly, which leads me to suspect that he is taking a very cautious approach.
Any and all insight is appreciated!
