chemical reactions of nitric acid

Stability - Pure nitric acid is not very stable. Even at ordinary temperature, in presence of sunlight it undergoes slight decomposition. As the temperature increases, the rate of decomposition also increases. On strong heating it decomposes completely to give nitrogen dioxide, ..

Thermal stability - On heating, HNO 3 decomposes to give NO 2..

The glass apparatus may break. A good quantity of the nitric acid gets decomposed at higher temperatures. At higher temperatures, potassium or sodium sulphates are formed, which cannot be easily removed from the apparatus. The reactions in the above method of preparati..

Iron displaces hydrogen from dilute acids and forms iron salts. Iron reacts with dilute sulphuric acid to form iron sulphate and hydrogen. Iron reacts with concentrated sulphuric acid to give iron (III) sulphate, SO 2 and H 2 . Iron reacts with dilute nitr..

Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidation of ferrous ion by KMNO 4 (potassium permanganate) in acidic medium..

Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example, the ..

Chemical Properties of Sulphur - With Acids - Sulphur does not react with hydrochloric acid. Dilute sulphuric acid and dilute nitric acid also do not affect sulph..

Understanding the Chemical Properties of Acids and Bases - As acids and bases are highly corrosive and reactive substances it is important to understand their reaction and responses on substances commonly found around us. It helps us to understand the outcome..
