Alkali earth metals hetero carboxylic acid salt?
Okay. So this may be a stupid question but multiple times have I asked myself this question and no matter what I search no information of hetero
carboxylic acid salts being a thing or not being a thing is anywhere. Each time I just drop it but enough is enough haha
Again, may be a stupid question

You mean a salt of different organikc acids?
E.g. Ca(CH3COO)(CH3CH2COO) ? This would be a mixed calcium acetate/propionate.
Maybe such things exist. They would be double-salts with multiple anions in the crystal lattice at a specific ratio. I am quite sure that such things
are possible. With other anions I know many examples, both with multiple anions and multiple cations. Some examples:
Anionic examples: NaK-tartrate; alum; Mohr's salt.
Cationic examples: Cu2CO3(OH)2 (mixed copper hydroxide/carbonate); BiOCl (bismuth oxide/chloride)
These are not complexes, they contain the separate ionic species, indepent from each other in the crystal lattice.
Their nature is different from complexes, e.g. Be4O(CH3COO)6 is not a mixed beryllium oxide/acetate, but it is a complex of very intricate structure
and can better be considered a covalent species as a whole. It is insoluble in water, but soluble in several non-polar organic solvents.

Yeah, exactly what woelen is saying. Specifically I was looking at calcium salt destructive distillation that mentions mixing 2 different calcium
salts together and distilling then for a relatively low yield. I was curious as to whether mixing the acids together first and then basifying them
would produce a better yield by possible forming a mixed carboxylic acid calcium salt. I couldn’t find anything about forming 2 different carboxylic
acids to a alkali earth metal cation

Whether you really get a mixed acid calcium salt or not, I do not know, but you will get a good mix of the two different cations. This will always be
better than the result of mechanical mixing.

This question has been asked often regarding this reaction.no u don't need the two different acids attached to the one calcium atom.u just use however
much of the 2 different salts.dissolving both in water then boiling to dryness will provide a better result than manual mixing but u could probably
get as good a result with a ball mill or one of those powder tumblers pharma companies use to mix powders together in before putting thru a pill
press.if I wanted to make the double salt though I'd mix equal mole of each acid then the equivalent amount of caoh in water then combine with rapid
stirring.i don't know whether "the stronger acid librates the weaker one" comes into play here or one fully neutralises the calcium first then the
other acid gets neutralised because ones more reactive or not.

@draculic acid69: Try to be a little more precise in use of capital letters, punctuation and correct usage of chemical symbols and formula's. Your
posts sometimes look just like an unstructured blob and I notice that I more and more am inclined to simply ignore your posts. Others may also have
that feeling. I don't think that this is what you want.

This is about the tenth time you've been a grammar nazi woelen. If I was on a computer with a keyboard It wouldn't be such an issue but when I'm on my
mobile (quite often) using my finger to hit tiny letters that aren't really there and dealing with autocorrect and im out and about moving around
proper punctuation and capitalization just aren't that high of a priority.Its obviously a pet peeve of yours but it is what it is.

No, I second woelen. I type most of my posts on my phone and it’s really not that hard. We’re not being grammar nazis, we’re just suggesting
that you make your posts more readable.
