ionization of hno3 in water

The apparatus is set up as shown in figure 6.15. The combustion tube is heated strongly and concentrated nitric acid is allowed to flow into it. Due to the heat, it decomposes, liberating the corresponding gases. Reddish yellow fumes of nitrogen dioxide, water vap..

Nitric acid from Air - Nitric acid can also be prepared entirely from the air. Air free from moisture and carbon dioxide is subjected to an electric arc whose temperature is around 3000 o C. At this temperature, nitrogen and oxygen of the air combin..

Aqueous nitric acid obtained by this method can be concentrated by distillation to 68.5% by mass. Further concentration to 98% acid can be achieved by dehydration with concentrated sulphuric acid. Anhydrous nitric acid can be obtained by ..

However in the laboratory, nitric acid is prepared by distilling a mixture of concentrated sulphuric acid and potassium nitrate or sodium nitrate salt (cheap and easily available). The apparatus is set up as shown in figure 6.13. Potassium nitrate or sodium nitrate is ..

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, ..

Uses of Nitric Acid - The important uses of nitric acid are as follows: 1) Nitric acid plays a significant role in the manufacture of various products such as: Explosives like trinitrotoluene (T.N.T.) nitro glycerine, gun cotton, ammonal e..
