Question

Do acids even react on nonliving things such as taj mahal turned to yellowish from white due to acid rains

Answer 1

Acids do react with non living things such as metals, non metals, bases etc.

Taj Mahal is situated in Agra. The air in this place contains serious levels of sulphur and nitrogen oxides due to the large no. of power plants and industries set up around this area. All these led to acid rain. Acid rain reacted with the marble (calcium carbonate) of Taj Mahal. This caused damage to its structure and the marbles turned yellowish in colour.
