Nitric acid (HNO3)

Nitric acid is known as nitric acid or nitric acid. Its molecular formula is HNO3 and its density is 1.51 g/cm³. In its pure state, it is completely colorless, but the accumulation of nitrogen oxides in it gives it a slightly yellow color. The gases released from this desiccant give it an unpleasant odor. This strong acid is highly soluble in water. It changes color to brown when exposed to sunlight.

Applications

• This material is used in aerospace, the explosives industry, in the production of chemical fertilizers such as calcium nitrate and ammonium nitrate, in the manufacture of various nitrate salts, as well as in the manufacture of dyes and medicines, and for the purification of various metals.

Maintenance risk

• This non-flammable acid is a strong oxidizer at high concentrations and generates heat when combined with fuels and alcohols. It can react with reducing agents or combustible organic materials and burn or explode.
• Contact with the eyes causes severe eye burns and contact with the skin causes slight skin irritation.
• Its respiratory effects are delayed and if swallowed, it causes pain and burns of the mouth, throat and stomach, and sometimes leads to death.

Storage method in plastonic tanks

• Polyethylene tanks can be used to store nitric acid with a maximum concentration of 30% and a maximum storage temperature of 60 degrees Celsius.
• The tank should be installed on a smooth concrete, asphalt or steel surface. No ropes or other means of securing the tank should be used around it, and ladders should not be connected to the tank.
• The fittings used in tanks for storing this material are polyethylene and polyvinyl chloride, and gaskets made of ethylene propylene diene monomer are used for sealing.
