This question is inspired from the following questions:
The answer to the 1st question says that calcium citrate is highly unlikely to form from calcium chloride and citric acid because of its inability to be present in deprotonated form and will not precipitate in acidic medium. 2nd question also addresses a similar kind of problem. But what about calcium benzoate?
Which calcium salt can succesfully precipitate calcium benzoate from benzoic acid? Would calcium hydroxide work for that? I am pretty sure calcium chloride won't work because it is a good dehydrating agent and would rip off water molecules to form something else. Calcium benzoate is also somewhat more soluble in water than calcium citrate. So, what should be the necessary measure to successfully precipitate calcium benzoate?
