Does potassium bitartrate have an inverse solubility/temperature dependance?


On this MSDS for potassium bitartrate
http://www.sciencelab.com/msds.php?msdsId=9927703
it says that it is "Partially soluble in hot water. Very slightly soluble in cold water." Is that true?

It has a normal solubility curve, see here;

Wines are frequently chilled to precipitate the potassium bitartrate before bottling, this makes the wine less acid and more physically attractive to customers.

Ah right. Thanks. Is it just me or does cream of tartar smell horrific? When a tiny amount of the powder gets in my nose it reminds me of that smell/taste I get in my throat when I have a lung infection.

I have never noticed that, but it might be just me :)

Note: Don't use sciencelab.com for MSDS, they are a scam company. One of our members even purged all the links from wikipedia and replaced them with legitimate suppliers

Soluble in hot water, slightly solube in cold is normal

Ah right, thanks for informing me. Are they a full on scam company as in you are 100% guaranteed to be ripped off if you deal with them?
