Which of the following agents is responsible for turning the Taj Mahal yellow?
(c) Sulphur dioxide
(d) Nitrogen dioxide
Answer: (c) Sulphur dioxide is responsible for turning the Taj Mahal yellow. It creates acid rain, which reacts with the Taj Mahal’s marble and damages it. The increased level of sulphur dioxide is due to a large number of power plants and industries set up in Agra. Sulphur dioxide is an odourless and colourless gas. It is a poisonous gas that contributes to air pollution. Volcanic activity releases it naturally. The burning of fossil fuels is the primary source of SO2. It quickly interacts with other substances to produce hazardous molecules such as sulphuric acid and sulphurous acid.
