Okay, so let's label some acids, bases, conjugate acids, and conjugate bases.
00:05
So the general thing we got to understand is that an acid is a hydrogen donor or something that loses hydrogen over the course of the reaction, and a base is a hydrogen accepter or something that's going to accept hydrogen over the course of a reaction.
00:18
So we kind of want to compare our reactants to our products.
00:21
And for nh4 to turn to nh3, it needs to have given an h plus to oh minus.
00:29
It needs to have lost in h plus and that goes over to oh minus to make water.
00:34
So on the reactin side is always where you'll have your acid and your base.
00:38
So the thing that donated the hydrogen is my acid.
00:41
So nh4 is an acid.
00:43
The thing that accepted that hydrogen is my base.
00:46
So oh h minus is my base.
00:48
Your acids and your bases will always be on your reactin side.
00:53
If we want to go on to the products side, we do the same thing.
00:56
We think about if this reaction went into the reverse, then the water would have to give a hydrogen back to nh3 to reform nh4 plus.
01:09
So what that means now is my conjugate acids and bases are going to be on my product side.
01:14
So the thing that's a hydrogen donor is water, so it's an acid.
01:19
But since it's a product, it's a conjugate acid because it's an acid that i made...
