Chemical properties of Limestone

Chemically, both limestone and marbles are siliceous calcium carbonate rocks.

Lime (CaO)38-42%
Silica (SiO2)20-25%
Alumina (Al2O3)2-4%
Other Oxides like Na, Mg1.5 to 2.5%
Loss On Ignition (LOI)30-32%

Limestone, like marble and other calcareous stones, are referred to as acid sensitive. Calcareous stones are readily dissolved in acid, therefore acidic products should not be used on limestone and marbles.
