- TL;DR Summary
- Is protonation in bases considered ionisation
Hi there,
I'm sure this is glaringly obvious for chem-buffs but just been coming across some Henderson-Hasselbach type questions in Basic scenarios where we're looking at basic solutions where calculating involves a [BH]/ as opposed to the regular [AH]/[A-].
I've come across wording in what I've read to make me think the [BH] form is considered ionised for bases hence the ratio eg 90:1 [BH]/ - 90%
I would assume in ordinary situations with [HA]/[A-] the % ionised would be the amount of A- (the ionic form) in solution and here 90:1 - 10%
Q: Is the resource I'm looking at wrong, is protonation in bases considered as ionisation or is my understanding of % ionisation wrong?
Thanks in advance,
David
