So, here we've got our nitrogen and it's got three bonds, right? So, is it going to want to do anything? absolutely, right? It can still attack, so we've got a lone pair that it can use to go ahead and grab a hydrogen off of this water, go ahead and do that properly, there we go, so then we know we kick electrons on to that O and we know that our water has two lone pairs and what we get is this right here with our nitrogen, right? Our nitrogen now has two hydrogens coming off of it and we've got a positive charge and no lone pair, right? And then we've got our hydroxides again with three lone pairs and a negative charge, okay? And not all of these reactions that happened that I drew up here, would actually occur because of pKa valence, right? But if they were to occur, this is how it would happen, so guys please feel free to let me know that if you have any questions, right? if not, let's move on.
