editI have no idea if anyone will read this, but I, out of boredoom just prepared a fairly clean sample of this chemical.I am going to do some research and improve this page. The material I have now is all powdery and a little yellow from impurities in the vinegar. I am going to recrystallize it and will post a picture once I have something that isn't offwhite dust.

Getting Calcium Acetate
editDoes anyone know where you can get some of this? I need some for a school project.

Someone check if this chemical's solubility decreases and temperature increases. This doesn't make sense intuitively. —Preceding unsigned comment added by 35.9.124.106 (talk) 00:34, 30 September 2009 (UTC)
- I tried making a 2 M solution (ie 35.2 g/100 mL) of the hydrate at 20 C and it didn't fully dissolve. I put at it 4 C and it mostly turned into a big hard slurry, like a hand warmer. So its solubility decreases as the temperature decreases. But I couldn't find a source for its solubility. ImproveEverything (talk) 13:52, 14 August 2024 (UTC)
- I think its solubility also decreased at high temperature (like 50 C from a hotplate), so I don't think they just swapped the 100 C and 0 C solubility ImproveEverything (talk) 14:03, 14 August 2024 (UTC)
Editing help - I just corrected the melting point information for calcium acetate and added a reference, but when saved, the new temperature came up, followed by this: Expression error: Unrecognized punctuation character "?" . I cannot see information for K and °F on the edit page, so am not sure how to solve this problem.

Structural Diagram
editI am not an expert but the structural diagram shown makes it look like the formula should be Ca(COOH)2 which is wrong. Compare with the Sodium acetate page. Can someone who knows this better than I please fix it? --Sbreheny (talk) 21:49, 19 January 2014 (UTC)
I just answered my own question - the diagram shown is correct. I didn't realize that it implied a Carbon atom on the dangling line on the left-hand-side. I knew Hydrogens were implied but not Carbon. --Sbreheny (talk) 21:57, 19 January 2014 (UTC)
