To determine whether or not a reaction occurs when aluminum sulfate, aluminum having a 3 plus charge, sulfate having a 2 minus charge, requiring two aluminums for every 3 sulfates, we need to react with sodium carbonate.
00:19
We need to know the solubility rules.
00:22
According to the solubility rules, most sulfates are soluble, so aluminum sulfate is soluble.
00:30
Most sodium species are soluble.
00:33
So sodium carbonate.
00:36
Sodium with a 1 plus charge, carbonate with a 2 minus charge, will require two sodiums per carbonate.
00:47
For these types of reactions of ionic compounds in aqueous solutions, their metathesis or double displacement reactions with a cation switch places.
00:58
So sodium is now going to go with the sulfate, and according to solubility rules, sulfates and sodium salts are soluble, so this will also be aqueous and will dissolve in the water...
