Where to look for solubility data?

I just spent 15 minutes looking for solubility data for the third time this month and it's been such a pain it motivated me to write this post.

I feel like every time I try to compare solubility of 2 compounds there is either only one temperature point (25C) in one, or things like acetone/methanol/glycerol are listed in only one of them, or they also have a single temperature point, or just says "slightly soluble" whatever that means.
The list could go on and on

As an example look at NaCl and NaClO acetone solubility,
NaCl has no mention of it in the usual place but some wierd table down at the bottom has it,
NaClO says "Sparingly soluble" but at least it's where it's supposed to be.

Usually I use wikipedia/smwiki or look through google images,
I also tried pubchem but it's even worse as it's in the form of citations that seem to be automatically generated as they are sometimes wrong/not related to question they should answer.
What do you guys use? Is there some secret website I don't know about where everything is in one place or do you also go through this journey each time you want to look things up?

Thank you, very neat website, this one had 2 sample points for nacl/acetone .
Although as you said, it's not perfect, naclo/acetone is "sparingly soluble" at 1 sample point, also a little hard to navigate.
Biggest let down is http because if your isp sees random chem queries that might get you a knock on the door, and trust me they will see it, 99% of traffic is over https so it will stick out like a sore thumb with webpage title and all, and that .ru tld .
I probably wouldn't use it just because of that.

Oh nvm you can connect with https

It could be a useful project, set a standard, say 5 or 10mL of H2O, acetone, ethanol, and whatever else is of interest, and then add x amount in increments of mg or g until saturation. Then you can just convert it into grams/liter or grams/mL.

This seems to be the source material most sites reference.
Although it's anything but pleasant to use, selecting solubility system from drop down menu with thousands of entries lol? Searching by text for NH4Cl givers me "Ammonium dihydrogenphosphate with Ammonium chloride and Water"

Then you can just convert it into grams/liter or grams/mL. I considered doing this but realized I don't have the means to do it. As in no lab, no temperature controlled heater/cooler, no time, no/few acs reagents so any results would be of little value. My example of NaCl/NaClO3 stems from the fact that I wanted to separate the product from my cell, assuming it's even present I cannot vouch for it's purity and testing anything other than a pure reagent is pointless. Quote: It surprises me that a better database doesn't exist. someone somewhere, some company has to have that data compiled already right? I think I'm gonna make myself one for the sake of convenience Quote: There's this: https://srdata.nist.gov/solubility/sol_main_search.aspx (digital IUPAC-NIST database) https://iupac.org/what-we-do/databases/solubility-data-serie... (scans of hard copy publications) This seems to be the source material most sites reference.

To obtain the solubility of different compounds at different temperatures, solvents, mixed systems, etc.
I always refer to

"Solubility Of Inorganic And Organic Compounds - A Compilation Of Quantitative Solubility Data From Periodical Literature By Atherton Seidell —
Second Edition, Enlarged And Thoroughly Revised, 1919"

It's almost a thousand pages filled with solubility data for various compounds arranged alphabetically, from simple salts to compounds whose names only the damn organic chemists could pronounce. It has tables with the solubility of 0 to 100 degrees Celsius, in pure water, various solvents, solvent mixtures, correction for anhydrous and hydrated salts, etc. Yes, it is a book from 100 years ago, but at that time they already had adequate instruments and standards to take fine measurements like these. If you compare the values ​​presented in the book with the values ​​in any modern database, you will see that they are identical or only slightly different. I will attach he download link for this book on the Internet Archive.

The copyright of the book has expired and therefore it is a work of free disclosure. I hope it's useful to you
