Hello, in this question we are asked to identify the spectator ions.
00:06
So we find spectator ions in a double replacement reaction, such as this one, and spectator ions are the ions that do not react.
00:20
The way we can tell that they do not react is they are exactly the same on the reactant side and the product side.
00:44
Okay, so we are setting out to identify our spectator ions here.
00:50
They're going to be the ones that are exactly the same.
00:52
That includes state of matter.
00:56
All right, well, let's see.
00:57
If we look at ag, ag is aqueous on the left, but on the right it's a solid.
01:03
So ag changes.
01:05
It is not a spectator ion.
01:08
Nitrate, however, is aqueous on the left, and guess what? nitrate is still aqueous on the right.
01:13
So that is one of our spectator ions...
