over basifying/acidifying solutions...
« on: April 05, 2009, 01:25:19 AM »
Is there any real threat in overbasifying/overacidifying solutions besides dragging in impurities from protonating/deprotonating?

Just curious..I've been thinking about this recently during A/B extractions and it's been on my mind.

Some organic substances are highly sensitive to acidic or basic enviroments depending on the substrate being used. Substances such as MDMA can be damages from being stretched two far in one direction or another by cleaving the cyclic ether. Yet substrates such as Methyl Amphetamines have a strong tolerance from one end of the PH spectrum to another.

Also if it can sometimes be a total hassle to have over basified if you decided to use something besides NaOH to basify the mixture, such as sodium carbonate as I learned early on.

I'm not sure about over-basifying, but over-acidifying can interfere with crystallization.
