List of Strong Acids

List of Some strong acids are as follows:

Hydrochloric Acid (HCl)

• Hydrochloric acid is an example of Strong acid.
• The chemical formula of Hydrochloric acid is HCl.
• Hydrochloric acid is aqueous solution of Hydrogen chloride.
• Hydrochloric Acid is prepared by dissolving hydrogen chloride and water.
• When hydrogen chloride gas enters the water, the water molecules take the hydrogen atom in HCl(g) and pull it away from the chlorine atom.
• It is a strong corrosive colorless acid with pungent smell.

Sulfuric Acid (H₂SO₄)

• Sulfuric acid is colorless and odorless strong acid that is corrosive in nature.
• This acid has wide variety of applications in real life.
• That’s why this acid is known as King of Chemicals.
• The boiling point of the acid is 611 K.
• The higher boiling point and thickness of this chemical is due to hydrogen bonding.
• Sulfuric acid is very good oxidizing agent.
• Concentrated sulfuric acid is a very strong dehydrating agent. Thus, this chemical is used for drying wet gases which do not react with the acid.

Nitric Acid (HNO₃)

• It is a colorless strong acid that emits yellow or red fumes.
• The chemical formula of Nitric acid is HNO_{3 .}
• The shape of Nitric acid molecule is planar, with the nitrogen atom attached to three oxygen atoms, one of which holds the proton.
• Other two N-O bonds are equivalent and show the resonance with double bond character.
• Its boiling point is 83 deg C.
• It slowly turns into yellow color as it gets older.
• It is a common reagent used in laboratories and an important chemical used in many industries to manufacture explosives and fertilizers.

Hydrobromic Acid (HBr)

• It is a colorless strong acid, which has chemical formula as HBr.
• HBr is very reactive in nature and corrosive to most of the metals.
• The boiling points of HBr is 124 deg C.
• Hydrogen bromide is a colorless gas with a strong smell, highly soluble in water, and significantly dissociated in an aqueous solution.
• It easily fumes in moist air.
• Hydrogen bromide gases are highly corrosive and can cause severe burns upon contact.
• Anhydrous hydrobromic acid is hazardous and is transported in high-pressure cylinders.

Hydroiodic Acid (HI)

• Hydroiodic acid is a strong colorless acid.
• The chemical formula of Hydroiodic acid is HI.
• Hydroiodic acid is aqueous solution of hydrogen iodide.
• The boiling point of HI is -35.4 deg C.
• The fumes of this acid irritate the eyes and skin and can corrode animal tissues.
• The gas hydrogen iodide is non-flammable and can be toxic if inhaled. Inhalation may lead to adverse health effects.

Perchloric Acid (HClO₄)

• Perchloric acid is a strong colorless acid.
• The chemical formula of perchloric acid is HClO_{4 .}
• The boiling point of perchloric acid is 203 deg C.
• It is a strong oxidizing agent and corrosive to tissue and metals.
• Owing to its strong oxidizing properties, this compound exhibits very high reactivities toward most metals.
• It is also known as Hyperchloric acid.
• Perchloric acid is used as an oxidizer in the separation of sodium and potassium.
• It is Used in making explosives.
• It is Used for plating of metals.

Strong Acid is an acid that completely dissociates in an aqueous solution, while Weak Acid is an acid that partially dissociates in aqueous solution. Examples of strong acids are Hydrochloric acid (HCl), Sulfuric acid (H₂SO₄), Nitric acid (HNO₃), Chloric acid (HClO3), Hydrobromic acid (HBr), Hydroiodic acid (HI), and examples of weak acids are Hydrofluoric acid (HF), Nitrous acid (HNO₂), Sulfurous acid (H₂SO₃), Phosphoric acid (H₃PO₄), etc.

In this article, we are going to discuss what strong acid is, the list of strong acids, what weak acid is, and the list of weak acids.
