Question

A strong acid known as the “King of Chemicals” is
1. Hydrochloric acid
2. Sulphuric acid
3. Nitric acid
4. Phosphoric acid

Answer 1

Correct Answer - Option 2 : Sulphuric acid

The correct answer is Sulphuric acid

• Sulfuric acid (H₂SO₄) is a strong acid with hygroscopic and oxidizing properties also sulfuric Acid is a mineral acid.
• The other names of sulfuric acids are Mattling acid or Oil of vitriol.
• Sulfuric acid has the properties of strong acidic nature and is corrosive.
• At higher concentrations, it acts as an oxidizing agent and dehydrating agent.
• Much of sulfuric acid is used for superphosphates, ammonium sulphate fertilizers (approximately 80%), although just 20% is used in the chemical industry.

 

• A total of seven acids are widely regarded as “strong” acids in the field of chemistry.
• The list of strong acids-
  • Hydrochloric acid (denoted by the chemical formula HCl)
  • Hydrobromic acid (denoted by the chemical formula HBr)
  • Hydroiodic acid or hydriodic acid (denoted by the chemical formula HI)
  • Sulfuric acid (denoted by the chemical formula H₂SO₄)
  • Nitric acid (denoted by the chemical formula HNO₃)
  • Chloric acid (denoted by the chemical formula HClO₃)
  • Perchloric acid (denoted by the chemical formula HClO₄)
• These acids are classified as strong acids because they (almost) completely dissociate into their constituent ions, which includes their anionic conjugate base and a proton when they are dissolved in water.
