Quick Answer: What Are The 3 Strong Acids?

What acids are strong acids?

Examples of Strong AcidsHydroiodic acid (HI): pKa = -9.3.Hydrobromic acid (HBr): pKa = -8.7.Perchloric acid (HClO4): pKa ≈ -8.Hydrochloric acid (HCl): pKa = -6.3.Sulfuric acid (H2SO4): pKa1 ≈ -3 (first dissociation only)p-Toluenesulfonic acid: pKa = -2.8.Nitric acid (HNO3): pKa ≈ -1.4.Chloric acid (HClO3): pKa ≈ 1.0..

Which is weakest acid?

Acetic acid is stronger than carbonic acid, and so on….Strong and Weak Acids and Acid Ionization Constant.AcidConjugate BaseHCl (hydrochloric acid) (strongest)Cl− (chloride ion) (weakest)H2SO4 (sulfuric acid)HSO4− (hydrogen sulfate ion)7 more rows•Jun 26, 2013

Which is strongest acid?

carborane acidThe world’s strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. Perhaps confusingly, it is also one of the least corrosive. The compound, called a carborane acid, is the first ‘superacid’ that can be stored in a bottle, say its creators.

What are three strong acids?

Examples of strong acids are hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other.

What are 3 weak acids?
