Why does ketchup dissolve aluminum foil?
Dear Cecil: I have recently experienced a phenomenon that a friend of mine declares has also happened to her. It’s rather ghastly. I covered a meatloaf with a ketchup glaze and stored the thing in the refrigerator covered with aluminum foil. Where the foil touched the meat I found that it was eaten away, dissolved somehow, leaving a gray aluminum puddle deposit on the glaze. Thinking it was a fluke I re-covered the meat loaf with another piece of foil and the same thing happened. What happened? — Ms. T.
