What are the steps for dissolving limestone?

Break the limestone sample to small pieces. Add vinegar or Coke or battery acid. Agitate. read more

The solubility of calcite (and hence of limestone) in pure water is very low, but is vastly increased in the presence of carbon dioxide. This gas, dissolved in the water to produce carbonic acid, permits dissociation of calcium carbonate, and dissolution rates and loads are therefore directly related to carbon dioxide content. read more

When carbonic acid comes into contact with limestone or calcium carbonate, it can cause it to dissolve over a long period of time. In nature, this reaction leads to the formation of caves. Vinegar, which contains about 5 percent acetic acid, is often used as an acid test for limestone. When limestone and acetic acid react, there is a fizzing reaction. read more
