Video Transcript

Hey guys, in this problem we need to go ahead and figure the conjugate base of ammonium. Remember, ammonium just looks like this NH4 plus, and we know that it would look something like this right, so I'm going to go ahead and just draw it up like this and we have our nitrogen has a positive charge, okay? Guys, real quick what's the pKa of a nitrogen with a positive charge? it's just 10, right? It's about 10. So guys, what do you think is going to happen here? obviously the nitrogen is going to get deprotonated so we're looking for the conjugate base, right? But super easy what we're going to end up with is just our NH3, our ammonia deprot, so we go from harmonium to our ammonia, right? here's our lone pair and we have a no formal charge. Alright guys, that's it, let's move on.
