Yes, Nitrous is an unstable acid and only exists in water.
Nitric acid is not a very strong acid. Adding distilled water will cause it to be more diluted. Its acidity does not change. However, to neutralize it, you do not need more alkali as compared to before adding the distilled water.
1-diluted : Fe+4HNo3ـــــــــــــــdilu. + heatــــــــــــ Fe(No3)3+2H2o+No 2-with concentrated no reaction occurs becase of the iron passivity which is due to the oxidizing property of the acid were a layer of the metal oxide is formed which is complete and non porous so it protects the metal from further reaction
When sodium fluoride reacts with diluted nitric acid, it forms hydrofluoric acid (HF) and sodium nitrate (NaNO3). This reaction is represented by the equation: NaF + HNO3 -> HF + NaNO3. Hydrofluoric acid is a weak acid that can be corrosive and toxic.
This is the easiest way, though not "scientifically correct":Liters concentrated HNO3 = [ 200 L diluted HNO3 * 10 % ] / [ 68% ] = 29.4 L of the 68%Take the calculated amount and carefully add this to 171 L of water while good mixing!(if you take 30 L (easier measurable!) in stead, then with 170 L water you get about 200 L of 10.2% diluted acid)
A dilute solution of nitric acid has a lower concentration of nitric acid molecules compared to a concentrated solution. This leads to the dilute solution having a lower acidic strength and being less corrosive. Concentrated nitric acid, on the other hand, has a higher concentration of nitric acid molecules, making it more acidic and corrosive.

What the product of an interaction between a metal and diluted nitric acid is depends on which metal is used. Most metals in this combination result in a metal salt and a hydrogen. Silver, however, creates three products when combined with nitric acid: nitrogen monoxide, silver nitrate and water.
in room temp it decompose .it make a clear soloution with diluted nitric acid

Nitric acid is dissociated in water in: (NO3)- and 2 H+.

Nitric acid is typically produced by the oxidation of ammonia with air in the presence of a catalyst at high temperatures. This process creates nitrogen dioxide, which is then dissolved in water to form nitric acid. Additionally, nitric acid can also be produced by the reaction of nitrogen oxides with water.
Magnesium Oxide + Nitric Acid -----> Magnesium Nitrate + Water. Hope this helps.
To perform neutralization for chloride determination in cosmetics, first dissolve the sample in distilled water. Then, add a few drops of methyl orange indicator to the solution, which will turn red in acidic conditions. Slowly titrate the solution with diluted nitric acid until the color changes from red to yellow, indicating that the solution is neutralized. The volume of nitric acid used can then be used to calculate the chloride concentration in the sample.
