IA Exploration Chemistry Unit – Acids, Bases and Salts; Rate of Reaction Topic – Corrosion of Marble due to Acid Rain Tentative Research Question – How does the Acidity of Rain affect the rate of corrosion in marble, particularly monuments subjected to acidic and harsh conditions such as in the Taj Mahal in Agra, India and the Leaning Tower of Pisa, Pisa, Italy? Justification – Monuments are an important and irreplaceable part of any culture. Countries pride themselves on these monuments and quite often, if not always, have these monuments become their mascots and icons on a global scale. These monuments are generally made with white marble and limestone as these were the wonder-materials that helped improve aesthetic but were also solid in nature. However, in today’s world, pollution is on the rise and acid rain has become more common. While governments are making sure that it doesn’t affect major modern infrastructure, these precious monuments are generally left in the dust. The impact of the acidity of the rain can and will help governments in preserving these monuments.
