Which chemical have I made? Answered

After my experiment which turned out to be lead oxide, I did something else.
I bought a lump of Calcite, and found out it dissolves in acid. Therefore, I couldn't resist breaking off some lumps and putting those in vinegar. For at least a week, there was no significant change in the container, but after another week, all of the vinegar was gone, and no sign of the calcite lumps either. only a white and a pink residue.

What I want to know is, is this Calcium? Or something else?

You made calcium acetate. Acetates are salts of vinegar. Kitchen vinegar often has some residues in it, sometimes it is colored by caramel,or it could have been made from wine. This might cause the pink color.

 yes it's defininitly calcium acetate.  It escapes me which chemical calcite is but, if it's either calcium carbonate, or calcium hydroxide, then they both make calcium acetate. It can't be calcium. 

.  CaCO3 + CH3COOH + H2O -> ?
.  As steveastrouk points out, you probably don't have elemental Calcium.  I'm guessing it's primarily Ca(OH)2

It HAS to be something else, because you can't produce free calcium without something getting very hot in contact with atmospheric moisture.
