Nitric Acid MSDS


Among different chemical compounds, formula for nitric acid is complex and difficult to understand. If you keep the nitric acid at a room temperature then it will be developing the yellow color. Nitric acid is a chemical substance in liquid state. Highly toxic for humans, the substance must be handled, stored and transported with great care. In order to manage all tasks involving this substance it is compulsory to read and apply the regulations detailed in the nitric acid MSDS, a document that includes all the necessary information for the safe handling, storage and transport.Below mentioned is a list of precautions and measures of safety, which are to be taken when exposed in Nitric Acid MSDS

Properties of Nitric Acid

Nitric acid MSDS reports that the substance burns in the presence of combustible materials, while in combination with organic products, metals and alkalis it can provoke explosions. Soluble in hot and cold water, the substance is not flammable and presents minimum risks of explosion. Nitric acid is a transparent, slightly yellowish liquid. It has an acrid, disagreeable smell, which can become choking after prolonged exposure.

Measures For Handling, Transportation and Storing Nitric Acid

The containers must  be made only of glass.  Metal and direct solar exposure is prohibited. According to the nitric acid MSDS, the substance must be kept in well ventilated spaces, away from any source of fire or flame, isolated from any incompatible substances and away from any source of heat.Nitric Acid Msds

Eyeglasses, neoprene gloves, boots and breathing apparatus are recommended by nitric acid MDSD for safety handling. When handling the substance, smoking and food consumption are not allowed. The handlers must wear special equipment, which prohibits inhalation, ingestion and substance’s contact with skin or eyes.

White is the code for storing Nitric Acid. The transportation can only be performed in special conditions and with proper inscriptions of the vehicles.

Hazards to Human From Nitric Acid

In case of skin contact, remove contaminated clothing and wash the area with cold water for at least 15 minutes, then cover the area in emollient cream. In case of eye contact, the nitric acid MSDS recommends removing any contact lens (if wearing) and flushing water for at least 15 minutes. The nitric acid can penetrate the human body through skin absorption, eye contact, ingestion (extremely hazardous) and inhalation (slightly hazardous).

If the substance is swallowed, do not provoke vomiting unless specified by medical personnel. For any of the above-mentioned situations, medical assistance is recommended immediately. Severe cases may need artificial breathing and oxygen administration. Disinfectant soap and anti-microbial cream can be used in severe skin contamination. For mild forms of inhalation, the nitric acid MSDS recommends exposure to open air and removing all breathing obstacles (collars, ties, waistbands or belts).

Health Hazards for Animals

The nitric acid MSDS does not report any particular effects on animals, although it is recommended to keep animals (terrestrial and marines) away from any contamination with this substance.

Hazards to Environment

Accidental spills may have negative effects on the environment. According to nitric acid MSDS, short-term degradation products are not frequent or likely to appear. It is possible however for the long-term degradation products to arise.

Nitric Acid Uses

The first thought which the ‘acid’ brings to your mind is corrosives, astringency, and ability to get diluted with other substances. It should be noted that all acids are not very destructive. There are some acids which are very dangerous and one of them is nitric acid. Nitric acid is considered to be one of the most destructive chemical compounds which are highly used in making fertilizers and explosives. It is used in fertilizers because of its ability to help plants grow faster. Moreover, this compound is used in various chemical and industrial processes also.

It has been an integral part of explosives and is derived from natural nitrate compounds which were then used as a fuel in German war before the beginning of First World War. This chemical compound is also used for making components of TNT (trinitrotoluene) as well as ‘Semtex’ which is a plastic explosive.

Nitric acid is an agricultural fertilizer which promotes rapid growth of plants but has some unfortunate side-effects. One such side-effect is that nitrates are water soluble and when sprayed during soil draining process, they mix with water and reach the rivers and streams. When in water, Nitric acid stimulates algae growth and deoxygenates water thereby hampering growth of animal life and other water plant forms. Nitric acid is a good oxidizing agent and hence used in the manufacturing of solid fuels for propulsion of rocket; some constituents of rocket fuel work as oxidizers also.

In woodworking, Nitric acid is used as aging agent where it has the ability to be used in a highly dilute form. Here, it changes the appearance of woods and gives similar color like that of traditional waxed or oiled surface. Nitric acid finds application in jewellery business where it is used for verifying low-grade alloys, checking gold contents’ purity, and many more.

For scratching metals for some surface, a solution of water and alcohol can be used. One of the main applications of Nitric acid is in dairy sectors and food processing sectors where it is used for removing magnesium and calcium deposits during the conversion or manufacturing process or which results due to reaction with hard-water.

Nitric acid has been known since 9th century but it was produced in abundance during the early 20th Century. This happened when Wilhelm Ostwald, a German chemist synthesized nitric acid. He, along with a German corporation BASF experimented with it. Both of whom have tried various attempts for producing nitrates which were used in weapons before World War I.

 

Nitric Acid Formula And Properties

Nitric acid, being a very strong acid is also known by names like Aqua fort-is and Nitre spirit. It is also known for its corrosive and highly toxic nature. You will find the chemical formula of nitric acid in almost all chemistry books. Pure nitric acid is colourless and old samples of nitric acid usually have a yellowish colour. Nitric acid obtains yellow colour when nitrogen oxides get accumulated in it. Nitric acid solutions which contain 85% or more nitric acid in them are known as nitric acid fuming. This nitric acid fuming can be categorized as red nitric acid fuming or white nitric acid fuming which is based on the amount of nitrogen dioxide present in it. On keeping nitric acid at room temperature you will see that it develops yellow colour which is due to the decomposition.

Nitric acid is a strong oxidizing agent and its chemical formula is HNO3. For cleaning spill caused as a result of some chemical reaction, you can neutralize it with acid neutralizer available in laboratories. Make sure that you carry out all the given instructions properly along with safety guidelines. For performing neutralization of nitric acid, you will first have to carry out titration using burette which will require sodium bicarbonate.

There are many other bases also. Nitric acid being pure and anhydrous has a density of 1.5 g/cm. It is mobile and colourless liquid which solidifies at -41 degree at which it forms white crystals. Its boiling point is 82 degrees. If its boiling takes place in light you will see that it undergoes partial decomposition and thereby forms nitrogen dioxide. You have to store nitric acid at a temperature below zero degrees for avoiding its decomposition. Nitrogen dioxide gets dissolved in nitric acid and changes its color from colourless to yellow or even to red.

Nitric acid is basically a harmful chemical compound that is acidic in nature. Spirit of nitrate and Aqua Fortis are two other names of Nitric acid. This chemical compound is highly corrosive as well as a toxic compound. The chemical formula of Nitric acid is HNO3. Its two main constituents are nitrogen dioxide and hydrogen. The acidic nature of Nitric acid is because of the presence of nitrogen dioxide. This chemical compound in its pure form is colourless and obtains a yellowish colour when exposed to different oxides of nitrates for a long time.

Some Properties of Nitric Acid:

  •  It is a colourless liquid in its pure form
  • Its density is 1.522 grams per cubic centimetre
  • This acidic compound solidifies at about -42 degree Centigrade
  • Boiling point of Nitric acid is 83 degree Centigrade
  •  So as to prevent its decomposition, Nitric acid is stored at 0 degree Centigrade
  •  At a very high temperature, this liquid compound obtains a yellow colouration which finally converts into red colouration
  •  It is strongly acidic in nature
  • Nitric acid has the capability to react with almost every metal and hence is used for acidic testing of metals in order to find their level of purity
  •  Nitric acid is formed when water reacts with nitrogen dioxide and the reaction goes as 3NO2+ H2O= 2 HNO3+ NO

In the above reaction you will find that Nitric oxide is evolved which in turn combines with atmospheric oxygen to form nitrogen dioxide and hence increases the compound’s acidic property. Nitric acid finds great use in manufacturing of fertilizers, explosive compounds, etc.
