Hi there.
00:03
In this question, we are given several substances and we want to know which one produces the greatest number of ions when one mole dissolves in water.
00:13
So let's look at the options that we have here.
00:15
Or let's look at each one in turn.
00:17
The first one is sucrose, c12, h -22, 011.
00:25
And as we look at that, we see that it is a molecule.
00:29
It's a molecular substance because it contains all non -metals.
00:34
Therefore, when we put it into water, we are going to get exactly one molecule.
00:40
Molecules do not break apart into ions when placed in water.
00:47
So we will just get one ion.
00:52
Well, it's not even an ion, but one particle for every c12h22.
00:56
That we put into water.
00:58
Let's look at the next one.
00:59
The next one is ionic.
01:01
We have ammonium with nitrate.
01:06
When this is placed into water, for each nh4, n .03 that we put into water, we get an nh4 ion, an ammonium ion, and we get a nitrate ion.
01:22
In other words, for every one nh4 n .o3, we get two ions.
01:29
All right...
