Solubility Chart

I came across this chart during a search which many should find useful. There are links to other charts included. It can be found at

Wow! That's handy!

Very handy indeed. Good old Ligma Aldrich.

Wikipedia's chart isn't half bad either:

I have regularly used the wikipedia page and often plotted solubility curves from it. Really nice to have an additional data set. I will look at other charts later. Worth bookmarking.

Unfortunately, ligma ballsdrich's chart has quite some mistakes making it look unprofessional. Density's unit isnt %! solubility values can't be negative! How come a chemical company didn't spot them before publishing?!:o I hope theyll fix them ASAP.

I found this on here a long time ago. I doubt you will ever need another one. Site can translate to english

Look at how these 2 have similar solubility:

NaCl: 35.8
KCl: 34.24

But with nitrates:

NaNO3: 88.3
KNO3: 31.66

Should I instead ask, why is sodium nitrate so high compared to potassium nitrate?

Good news for hotdog lovers!

I start by saying that the simplest method to find information regarding the solubility of a substance is by looking at the tables that you have reported but if you want to find information regarding a particular compound that is not very common (like some transition metals salts, gaseus substances or organic compounds) there is this website called "IUPAC SOLUBILITY DATA SERIES" which is basically a huge FREE online database about the solubility of many many substanes, literally any substance you can think of.

It is a website created by the IUPAC in collaboration with the NIST that collect the data coming from many reaserch papers into pdf files that can be easily downloaded

Here is the link:

Unfortunatly the site is not very intuitive but i will explain how it is organized:
The website is divided in to 4 sections called "Volumes 1-19" (first section), "Volumes 20-38" (second section), "Volumes 39-65" (third section) and "Volumes 66-103" (fourth section).

In order to find the compound that you are interested in you need to look for its name or the class to which it belongs (example: if you want to know the solubility of sodium metal you need to look for "sodium" or "alkaly metals") within the 4 sections.
Onces you have found the compound or its class (there may be more than one) you just need to click on the right hand side to download the pdf file.

Consider that:
- in the 1° and 3° sections the pdf file is already available, so you only have to click on the right hand side of the page.
- in the 2° section if you click on the the right hand side of the page no pdf file will be downloaded, insted you will access a second page in which you need to choose your specific compound and then you can download your pdf file.
- in the 4° section the pdf files are not available becouse you need to have access to the "journal of physical and chemical reference data".

I know that this website it may be a little bit complicated to understand at first, but ones you have tried to look for one or two compounds it will become really easy to use!

there is actually a way to access the pdf files of the 4° section (or any type of reaserch paper you don't have access to): just use Sci-hub!
Ones you click on the right hand side of the page you will find the issue of the paper that you are intresed in. Copy the link of that page and paste it into the search bar of the Sci-hub website, press enter and voìla you have your pdf file.

You cannot beat 'an old' line chart to compare solubilities IMO.

Another way to look up solubilities in google is to enter: the system (say ) sodium Chloride and (say) water

going to google scholar will give you some more results sometimes.
