So, I wanted to make calcium acetate, through the reaction of calcium carbonate and vinegar.
My proposed reaction:
$$\ce{2CH3COOH(aq) + CaCO3(aq) -> Ca(CH3COO)2(aq) + CO2(g) + H2O(l)}$$
It seems that there is not much reaction between the chalk (source of $\ce{CaCO3}$ and the vinegar (source of acetic acid), except intermittent particles of chalk floating to the top.
The vinegar I am using is white distilled vinegar, with a $95\%$ concentration. I diluted it because the amount of chalks I would be using would not fit the amount of vinegar that would come from the $95\%$ solution.
Quantitatively, I'm using $11.4~\mathrm{ml}$ of vinegar (before dilution), and $11.4~\mathrm{g}$ of chalk. I have left it for over a day, but still there has not been much apparent progress.
What should I do? I tried heating up the solution in hopes of increasing the rate of reaction, but calcium acetate is less soluble in hot water than in cold water.
I do not want to precipitate the calcium acetate out of the solution, and onto the calcium carbonate sediment at the bottom.
