1) What is the initial pH of the nitric acid solution?Nitric acid is a strong acid and therefore dissociates almost completely in water. The concentration of the hydronium ions must be .2M as well. This concentration yields a pH of (4) pH = -log[H3O+] = -log(.2) = .7

The pH of an acid depends on its concentration. pH stands for the -log of the concentration of H+ ions. Nitric acid is a strong acid, so it completely dissociates in water. You can tell if an acid is strong or not by the number of Hs and Os. If it has at least 2 more Hs than Os, it is a strong acid. The chemical formula of Nitric acid is HNO3, so it is strong.

Because HNO3 is a strong acid, every mole of it dissolved results in one mole of H+ . So to find the pH of a given concentration of HNO3, you need only find the -log of the concentration. You can do this with any calculator.

For example, the pH of .25M Nitric acid would be 0.60.

That would depend on the molarity of the nitric acid. Something like .0000001M nitric acid would be a little less than 7. A stock solution (Something like 15M) would be somewhere around zero, or perhaps into the negatives (this is possible.) Nitric acid ionizes almost completely, making it a very strong acid.

The pH level of Nitric acid is 3. However, in schools it has been diluted for safety issues so it has a pH level of 4-5.

It depends how concentrated the acid is. Common school laboratory Nitric acid (1 mol dm-3) should have a pH of around 2-3

There is no pH value for insoluble gases like N2, H2, O2, because there is no proton donating capacity in those molecules. So even IF they where soluble pH wouldn't be influenced by those.
