How does a mint dissolve with vinegar?

When a mint dissolves in vinegar, the acetic acid in the vinegar reacts with the compounds in the mint, particularly the sugar and flavor oils. This reaction breaks down the mint's structure, allowing the volatile oils and sugars to dissolve into the liquid. The effervescence often observed is due to the release of carbon dioxide when the acid interacts with any carbonates present in the mint. Ultimately, this process results in the mint losing its solid form and flavor compounds infusing the vinegar.
