Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. It is commonly used in the production of fertilizers, explosives, and dyes, as well as in metallurgy, metal cleaning, and electroplating. It is also used in laboratory settings for a variety of purposes.
When exposed to nitric acid, rubber may suffer from swelling and cracking, as well as discoloration and reduction in flexibility and strength. The acid can also cause the rubber to become brittle and more prone to breaking. In extreme cases, nitric acid can completely dissolve rubber, leading to catastrophic failure.
