What is the process of making nitric acid with platinum

ECHEMI 2022-09-21

Making nitric acid with platinum is a good way of making nitric acid for industrial use and for scientific research. It is also a good way of doing this to make nitrate from ammonium chloride, which can then be used as fertilizer. Making nitric acid can be done by reacting platinum with hydrochloric acid in the presence of steam. This reaction releases hydrogen gas, ammonia, water vapor and oxygen gas in the form of nitrogen dioxide. Iron or nickel may also be used to produce nitrogen dioxide but the process is more complicated than using platinum which makes it less economic to use them instead.

What are the uses of nitric acid

1. It is a powerful oxidizing agent.

The use of nitric acid in industry is extensive and it is used to make other chemicals such as nitrates, all the way down to ammonium nitrate, which is a fertilizer. Nitric acid is also used as a de-icing agent on roads and railways and as an oxidizing agent in the basic nitrogen fertilizer.

2. It is used in the production of chemicals for research.

The use of nitric acid in research is also very extensive and respected, and it is used to make various chemicals such as dinitrogen pentoxide, all the way down to complex organic compounds. It can also be used to make explosives such as TNT and nitroglycerin.

3. It can be dissolved in water to store it if necessary .

Nitric acid can be dissolved in liquid ammonia or liquid sulfuric acid which then makes it more convenient to store as they can both be stored at room temperature and will not corrode containers like glass or metal. Nitric acid will react with the glass or metal eventually and this can be used as a test to see if it has reacted with the container.

4. It can be mixed with other chemicals to form new chemical compounds

Nitric acid is used at high temperatures in processing some industrial metals such as lead, tin, copper and zinc, which are all metals that are resistant to the corrosion caused by nitric acid. It is also used in combination with sulfuric acid because it lowers the melting point of quartz and is also used in photographic developers which rely on quick reactions between compounds of developing agents. The color of photographic prints or films can be controlled by using different combinations of chemicals containing nitric acid.

Physical features of nitric acid

1. It is a colorless, transparent liquid

This is a highly volatile chemical and it is a solid at room temperature but it is a liquid which evaporates easily. It has a flammable nature because it can cause fires and explosions if it builds up in the presence of oxygen. This is why making nitric acid with platinum if important.

2. It is alkaline up to pH 11 or 12

The pH of nitric acid ranges from about 0 to about 11, which makes it slightly alkaline, but this depends on how much water is present as well. Above pH 10, each molecule will break down into oxygen and nitrogen at the same time into nitrogen dioxide gas.

3. It is soluble in water up to a certain amount.

Nitric acid will dissolve in water until it reaches a certain concentration, which depends on its concentration and temperature. Although this solution can be used as a dilution agent, nitric acid cannot be used as a high concentration solution because it is unstable.

4. It has low combustion point

It burns at about 150&#2013266052, which means that it does not react with oxygen easily in the air and if you drop nitric acid onto metal, the metal will corrode quickly even if it does not get hot enough to glow red at room temperature like an oxy-fuel welding torch can do.

5. It has strong corrosive properties.

Nitric acid is a strong corrosive agent and it can corrode most metals, even those that are normally resistant to the corrosion caused by sulfuric acid and it is also corrosive to the skin. It is corrosive to many substances as well such as glass, concrete and starch-based clothing alcohols and other organic compounds like plastics. This makes it very dangerous to work with in large quantities because you must use good containment equipment at all times as exposure guidelines have been set up regarding safety equipment needed when working with this chemical.

In conclusions, making nitric acid with platinum is a good way of making nitric acid for industrial use and for scientific research. It is also a good way of doing this to make nitrate from ammonium chloride, which can then be used as fertilizer. Making nitric acid can be done by reacting platinum with hydrochloric acid in the presence of steam.
