Limestone or marble is severely affected by the acid. Acid rain causes corrosion of all building and sculpture that are made up of marble. The sulphuric and nitric acid in the acid rain reacts with the calcite in the marble to dissolve it. This leads to peeling of marble structure which further exposes black crust made of gypsum formed by the reaction between calcite, water and sulphuric acid.
