Can vineger eat a egg shell?

Yes, vinegar can dissolve an eggshell. The eggshell is mainly composed of calcium carbonate, which is a carbonate salt that reacts with acids to form carbon dioxide gas. When an eggshell is placed in vinegar, the acetic acid in the vinegar reacts with the calcium carbonate to form carbon dioxide gas bubbles. These bubbles cause the eggshell to fizz and eventually dissolve.

The rate at which the eggshell dissolves depends on the concentration of the vinegar and the temperature of the solution. The higher the concentration of the vinegar and the warmer the solution, the faster the eggshell will dissolve.

Vinegar can also be used to dissolve other objects made of calcium carbonate, such as seashells and coral.
