Solubility Chart and Solubility Rules

The Solubility Chart and Solubility Rules are two ways to determine if a substance is soluble in water. Both are based on observations and measurements of different substances dissolving in water.
Looking at the Solubility Chart we can some up with a list of patterns for which substances will dissolve in water. These patterns, and the exceptions, can be condensed into a set of rules. These rules are what we call the Solubility Rules.
In this video we look at the the patterns in the Chart in order to familiarize ourselves with the Rules. Remember, both are telling the same story and are based on observations of what actually happens in the real world.
The Chart can be found at: en.wikipedia.o...
These are some of the basic rules for solubility ( • Solubility Rules: Exp... ):
Salts of:
- Group I elements (Li+, Na+, K+, Cs+, Rb+) are
- NH4+ (Ammonium ion) are soluble.
- the nitrate ion (NO3-) are generally soluble.
- of Cl-, Br-, and I- are soluble. Exceptions Ag+, Pb2+, and (Hg2)2+
- most sulfates are soluble. Exceptions: Ba2+, Ca2+, Pb2+, Ag+, Sr2+
- most hydroxide salts are only slightly soluble. Exceptions: NH4+, Li+, Na+, K+
- most carbonates (CO32-) are insoluble. Exceptions: Group 1 and NH4+
Note: Rules at the top supersede any lower rules.

These videos you make are pricelessly helpful. I hate to be a student who complains about my professor but their ability to teach is lackluster, leaving me to try and digest the material on my own. These videos really help break it all down in order for me to better understand the material. Thanks!

Thanks for the kind words!

what does the red S mean

Your video was very helpful. Thank you

[@wbreslyn]

Excellent!

Hello Mr b ! Your videos have been a blessing ❤ I have a doubt, what does the sS mean on the chart ?

[@wbreslyn]

That means "slightly soluble". Often, for example with net ionic equations, we consider this to be effectively insoluble.

I did some checking with my solubility table. In my country it's bigger and also we're required to memorize colors of everything. 0:30 My table says that Li3PO4, LiF and Li2SiO3 are insoluble. It doesn't have Cs and Rb so I'm not sure about them. 1:07 NH4PO4 and NH4SiO3 do not exist. 1:29 Sn(NO3)2 decomposes in water. 1:47 HgCl2 is soluble. CrI3 and SnI2 are insoluble. SnBr2 decomposes in water. FeI3, CuI2 do not exist. 2:23 HgSO4 reacts with water. 2:57 Ba(OH)2 is soluble.

Interesting! The table in the video is a subset of this table here: en.wikipedia.org/wiki/Solubility_chart To some degree most everything dissolves a small amount, so at some point these tables make a somewhat arbitrary distinction about sol vs. insol vs ss. In a practical sense I suppose it depends on the context of use.
