Question

nitric acid properties ​

Answer 1

Answer:

Physical properties: Nitric acid is a liquid with an acrid, pungent and suffocating odor. There are different concentrations of nitric acid available, and they are colorless, yellow or red accordingly. The industrial grade is about 68% in water, commercial grade is between 52% and 68%, fuming nitric acid is 86% or higher, while concentrations above 95% are called white fuming or red fuming nitric acid.

Chemical properties: Nitric acid is a strong, monoprotic acid. It readily forms solid hydrates such as the monohydrate (HNO3·H2O) and the trihydrate (HNO3·3H2O). Nitric acid can be decomposed by heat or light as shown below:

4 HNO3 → 2 H2O + 4 NO2 + O2.

It is a powerful oxidizing agent, and reacts violently with many non-metallic compounds. It also reacts with metals to dissolve them, form metal oxides, etc.

Chemical property:-

__________________

• Pure nitric acid is unstable to heat or sunlight it decomposes to give yellow solution due to formation of Nitrogen dioxide does hundred percent of nitric acid is not generally used.
• Nitric acid is a very strong monobasic acid.
• Nitric acid vigorously oxidises non- metals, metals, organic compound and organic compound.
