Hello.
00:03
In this equation, we have these two reactants given to us, and we want to complete this equation if a reaction occurs.
00:14
So we see that we have two ionic compounds here.
00:18
So this is going to be a double replacement or double displacement reaction.
00:23
Both of those names mean the same thing, but they just will differ from textbook to textbook as to which one they use.
00:29
Either double replacement or double displacement.
00:32
And this type of reaction has the general form, ab plus xy, and the ions exchange partners.
00:44
So a goes with y, the positive ion from the first with the negative ion from the second, and then x, the positive ion from the second, goes together with the negative ion from the first.
00:58
However, a reaction only occurs if you get an insoluble problem.
01:05
Product.
01:13
So what that means is a precipitate, a liquid, or a gas.
01:30
Okay, so going back to our original question here, we want to look at the two new possible combinations to see if either one of those forms an insoluble product.
01:44
So the first option is sodium with nitrate.
01:49
All nitrates are soluble.
01:51
So sodium nitrate is soluble...
