Nitric Acid 68%

5 Dilution When diluting nitric acid always add acid to water slowly to minimize the risk of splashing and heat generation Similarly to sulfuric acid water should never be added to concentrated nitric acid as it can cause a violent reaction

6 Safety Nitric acid should be stored in tightly sealed containers away from organic materials and reducing agents to prevent reactions Spills should be neutralized with a suitable base

7 Environmental Impact Nitric acid can be harmful to the environment if released improperly especially due to its ability to react and release nitrogen oxides NO which contribute to air pollution and acid rain

In summary 68 nitric acid is a versatile chemical used in a wide range of industrial and laboratory applications but it must be handled with care due to its corrosiveness and oxidizing properties
