In this question, we're asked to compare whether fe3 plus or fe2 plus is more acidic as a lewis acid.
00:09
So let's consider how metal ions are acidic.
00:13
And so what happens is in water, they're going to form adducts or complex ions with water molecules.
00:22
And so i would say both of these would tend to have, i would guess if this would have six water molecules around it.
00:29
And this would probably have six or four.
00:32
And this is just something that is determined by experimenting.
00:34
But we're only going to draw one here where i'm going to draw a water molecule here.
00:41
And so the way these metal ions are acidic is that what they do is they pool more electron charge towards them because they're positive electrons are going to be attracted to them.
00:55
So this is the flow of electrons going towards the metal atom.
00:59
And so then there ends up being a partial positive charge...
