In this question we need to predict our products and balance the equation when we react two aqueous ionic compounds.
00:11
So two aqueous ionic compounds reacting tell us that this is a double replacement reaction because in a double replacement we have our two aqueous ionic compounds and what they do is they exchange ions.
00:27
So ab plus xy they're going to exchange ions so the positive ion from the first goes with the negative ion from the second and the positive ion from the second goes with the negative ion from the first.
00:41
In order for us to have a reaction here one of our new products must be insoluble.
00:48
So we must form an insoluble product out of one of these two anyway in order for this to be a reaction.
00:58
If both of the new products are soluble then it would be no reaction.
01:07
Okay so let's look at our actual compounds here.
01:10
We have potassium hydroxide starting out aqueous reacting with aluminum chloride also starting out aqueous.
01:22
When they exchange ions the potassium will go with the chloride.
01:27
Well potassium has a positive one charge chloride has a negative one charge so therefore these are correct just as kcl.
01:37
Our other product then is going to be aluminum with hydroxide...
