Product introduction:
Nitric acid is a chemical compound with the chemical formula HNO3 and a molecular weight of 63.01. Pure nitric acid is a colorless liquid with a pungent smell. Concentrated nitric acid is a mixture. The mass fraction of commercially available concentrated nitric acid is about 68%, the density is about 1.4 g/cm3, and the boiling point is 83 °C. It is volatile and can be dissolved in any proportion Water, similar to sulfuric acid, will release a lot of heat when it is miscible, so it needs to be stirred constantly, and only concentrated nitric acid can be added to water, not the other way around. Nitric acid with a concentration of (86~97.5%) and 98% is called "fuming nitric acid". Because this acid is more volatile, it will form white mist when it encounters humid air. It is corrosive and toxic. Pay attention to wearing polyethylene plastic gloves and special Face mask.
Security measures:
1. Do not inhale mist, steam or spray.
2. If it touches the eyes or skin, wash it immediately with plenty of water and seek medical treatment as soon as possible.
3. All contaminated clothing must be taken off immediately.
4. Wear appropriate protective clothing, protective gloves and masks.
5. When storing concentrated nitric acid, it should be separated from reducing substances.
