Hi there.
00:03
In this question, we are given this double displacement reaction, and the entire reaction has been written for us and balanced.
00:11
But what we know about double displacement reactions is that there is only a reaction if we form an insoluble product.
00:20
So that's either a precipitate, which is indicated by the state of matter s for solid, or a liquid, which is indicated, of course, with an l or a gas, which is indicated with a g.
00:42
So we only have a reaction if we get one of these formed.
00:47
Well, if we look at what we're forming here, we just have an aquaous solution and an aquaist solution.
00:56
In other words, nothing has changed.
00:58
We still just have all four of these ions floating around in solution.
01:03
We did not form a precipitate, we did not form a liquid, we did not form a gas...
