What metals will nitric acid dissolve?
Aluminum does not react; there is a barely perceptible reaction with zinc; and a strong reaction with copper continues. Concentrated nitric acid is a very strong oxidator capable of reacting with the noble metals such as copper or silver (not gold, however).
Nitric oxide is a gas that is inhaled. It works by relaxing smooth muscle to widen (dilate) blood vessels, especially in the lungs. Nitric oxide is used together with a breathing machine (ventilator) to treat respiratory failure in premature babies.
- Nitric oxide supplements don't actually provide nitric oxide, which is a gas, but generally contain L-arginine which can, in some people, increase nitric oxide. Nitric oxide, in turn, potentially increases blood flow to muscles and other organs. In trained athletes the supplements appear to do little.

- Nitric oxide has gotten the most attention due to its cardiovascular benefits. Little did he know nitroglycerin acts by releasing nitric oxide which relaxes narrowed blood vessels, increasing oxygen and blood flow.
Chemically, nitric acid is made by bubbling nitrogen dioxide into water. So the objective in this approach is to generate nitrogen dioxide. This can be done by reacting hydrochloric acid, a nitrate salt and copper.
- Why are acids weak or strong? A strong acid is completely dissociated in water while a weak acid is in equilibrium with its conjugate base in water. Let's look at the reaction of a strong acid, nitric acid or HNO3, and a weaker acid, nitrous acid or HNO2, in water.
- HNO3 is a strong monobasic acid which releases one mole H+ on dissociation of one mole acid in aqueous medium. Its name is nitric acid. Concentrated HNO3 acts as a very strong oxidising agent and dilute HNO3 behaves as an acid. The gas evolved depends on concentration of HNO3 taken.
- Nitric acid is a colorless to yellow or red liquid sometimes fuming reddish brown vapors with a suffocating odor. Nitric acid is soluble in water with release of heat. Nitric acid is corrosive to metals or tissue.
