What is the pH of Concentrated Nitric Acid?

What is Nitric Acid? What is the pH of Concentrated Nitric Acid? What is the Difference between Concentrated and Strongest Acids? Can Ph turn Negative?
what is the pH of concentrated nitric acid

Pure water is the name given to any substance that has been neutralized. The pH of those substances is 7. It becomes increasingly alkaline as the pH level rises. Acids with a pH of 7 are less alkaline. If you are not aware of what is the pH of concentrated nitric acid and whether is concentrated nitric acid a strong acid or not, let’s read about it together!

1. What is the pH of Concentrated Nitric Acid?

The nitric acid’s chemical formula is HNO3. It has a pH level of 1.2 for a concentration of 68% type. For 0.001M solution, it is 3. (See How are elements and compounds similar and different?)

2. What are the Uses of Nitric Acid?

Nitric acid is used the same as sulfuric acid. Nitric acid is used in the production of ammonium nitrate, dyes, and plastics. If the nitric acid is mixed with HCL it forms a fuming liquid, known as aqua regia which is used especially to dissolve gold and platinum. (See How Acidic Is Stomach Acid?)

3. Is Concentrated Nitric Acid a Strong Acid?

Yes, concentrated nitric acid is stronger because nitric acids dissolve in water, nitrogen dioxide, and also with oxygen. It forms a brownish-yellow solution. This is called a strong acid because it is completely ionized into hydronium which forms a strong solution. It is a highly corrosive mineral acid and it turns blue into red. It dissolves with the ions in water and produces hydrogen cation. (See Gases that change your voice)

4. How do You find the pH of Nitric Acid?

Let’s find what is the pH of concentrated nitric acid for 0.001M of its solution,

So, [H]+= 0.001

pH = − log [H]+

pH = − log [0.001]

pH = − log [10]-3

pH = (−)(−3) log 10

pH = 3.

The pH of 0.001M of the nitric acid solution is 3. Also, check out What are the Monomers of the Carbohydrates Lipids Proteins and Nucleic Acids?

5. What are Acid base Titrations?

The acid-base titration is the measured volume of an acid which is known as concentration. If the concentration is titrant, then the other concentration can be determined. The pH of the titration solution adds to the base of the titration curve. Must see What are the Components of Water?

  • Concentrated Acid: Concentrated acid is a type of solution which has a high amount of acid molecules per volume of the solution. Concentrated means the high amount of elements present in a particular mixture. It has a maximum amount of acid molecules which are known as solutes, these molecules are dissolved in water for the acid solution.
  • Strong Acid: Strong acids are those which can be separated and ionized in a solution. Therefore, the strong acid will have a higher capacity to release protons. The aqueous solution releases protons which combine with the water molecules and forms hydronium ions, H3O+. These are done depending on the number of protons released per acid molecule.

7. Which is the Strongest Acid?

The strongest acid is the fluoroantimonic acid, SbHF6. It can be formed by mixing hydrogen fluoride and antimony pentafluoride. It is a super acid known to human beings. The pH of this acid is −31.3. (See What is Calcium made of?)

8. Does Eggs have pH Value?

Eggs have neutral pH; egg white has some parts which are naturally alkaline. The pH value can be as low as 7.6 at the time of laying. It can reach to a pH of 9.22 which can influence the pH of the egg. Must read Where are Most Triglycerides Stored in the Body?

9. How is Nitric Acid formed?

Apart from learning what is the pH of concentrated nitric acid, note that nitric acid molecules consist of 3 oxygen atoms, 1 nitrogen atom, and 1 hydrogen atom. The center nitrogen atom is attached to one of the oxygen atoms. The last oxygen atom is the nitric acid molecule, which has a charge of −1 and is bonded to the central nitrogen atom. It is formed when nitrogen oxide reacts with water. (See How does Calcium Chloride react with Chlorine?)

10. Can pH be Negative?

As you are aware of what is the pH of concentrated nitric acid, you must know that pH can be negative. It is not something that can be easily seen in the lab. The pH scale runs basically from 0 to 14, which can be easily calculated as a negative pH. 

Nitric acid, which has the chemical formula HNO3, is an extremely potent acid. It is also referred to as aqua fortis and the spirit of niter. Although it is essentially colorless, a yellow cast could develop. It is a poisonous chemical that can burn skin, react with hydroxides and other metals, and cause skin burns. The pH level of nitric acid (68% concentration) is 1.2, and this level can occasionally go negative. I hope you found this article on how do you find the pH of nitric acid useful.
