There, in this question we are reacting two aqueous ionic compounds.
00:07
That makes this a double replacement reaction.
00:11
You may know them as double displacement, the two terms mean the same thing.
00:17
But in this type of reaction, these two aqueous ionic compounds, which i'm representing as ab and xy, they exchange ions.
00:26
So what we get is the positive ion a combining with the negative ion y, and then the positive ion x combining with the negative ion b.
00:38
Okay, and by definition we only have a reaction if one of these new products is insoluble.
00:45
Okay, so that's what we want to know is what is the insoluble or the solid product formed.
00:53
So insoluble is going to mean our solid, or in other words a precipitate.
01:03
And we can determine this by using the solubility rules.
01:09
But before we use the solubility rules, we have to determine what our possible products are for this reaction.
01:18
So let's go ahead and write that out...
