Question:
Can acid rain damage buildings?



Replies:
Yes. Try putting a few drops of vinegar (an acid) on some baking soda (a basic) and notice what happens to the baking soda - it dissolves. Baking soda is sodium bicarbonate (try it with and Alka-Seltzer tablet too, the same thing happens). The same thing happens when limestone or cement (made of calcium carbonate) come into contact with the sulfuric acid and nitric acid droplets in acid rain. You can see evidence of this in big cities where carvings and statues have been dissolved by acid rain to the point that you can no longer read the message in the carving or recognize the face on the statue.
