Answer 2

The following happens to occur when dilute sulphuric acid reacts with marble piece -

• Marble is made of gypsum. Gypsum is calcium sulfate. When it reacts with sulphuric acid it forms a protective barrier on the surface of the marble so that no more damage occurs to the marble.
• Sulphuric acid is present in acid rain or polluted air. When this rainfall on the marble of any monument, the calcite dissolves, and a black crust is formed. This black crust is formed when calcite reacts with sulphuric acid and water.
• It tends to destroy the natural structure of marble and tends to destroys the beautiful monument.
• Due to pollution sulfate and nitrate present in air reacts with water to form sulphuric acid and nitric acid, and so when rain occurs it will fall on the marble.
