What will happen if you put fluorite in vinegar?

Fluorite (CaF2) is a relatively unreactive mineral, and vinegar (a dilute solution of acetic acid, CH3COOH) is a weak acid. As a result, there is no significant chemical reaction between fluorite and vinegar.

However, if fluorite is finely powdered and added to vinegar, the mixture may produce some effervescence due to the release of carbon dioxide gas. This is because acetic acid can react with calcium carbonate (CaCO3), which is a common impurity in fluorite, to produce calcium acetate (Ca(CH3COO)2) and carbon dioxide gas (CO2).

Here's the chemical equation for this reaction:

CaCO3 (s) + 2CH3COOH (aq) → Ca(CH3COO)2 (aq) + H2O (l) + CO2 (g)

The effervescence will be more noticeable if the fluorite sample contains a significant amount of calcium carbonate. Fluorite itself will not react with vinegar to produce any gas or precipitate.
