What is the order of acid strength from strongest to weakest?
Acid Strength and Bond Strength The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5).
What are the 7 weak acids?
Weak Acid
- Acetic acid (chemical formula: CH3COOH)
- Benzoic acid (chemical formula: C6H5COOH)
- Oxalic acid (chemical formula: C2H2O4)
- Hydrofluoric acid (chemical formula: HF)
- Nitrous acid (chemical formula: HNO2)
- Sulphurous acid (chemical formula: H2SO3)
- Phosphoric acid (chemical formula: H3PO4)
Which acids are strong and weak?
The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid. The only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF).
What are the strongest acids in order?
List Of Top 7 Strong Acids

- Chloric Acid (HClO3)
- Hydrobromic Acid (HBr)
- Hydrochloric Acid (HCl)
- Hydroiodic Acid (HI)
- Nitric Acid (HNO3)
- Perchloric Acid (HClO4)

What are 3 weak acids?
Some common examples of weak acids are listed below.
- Formic acid (chemical formula: HCOOH)
- Acetic acid (chemical formula: CH3COOH)
- Benzoic acid (chemical formula: C6H5COOH)
- Oxalic acid (chemical formula: C2H2O4)
- Hydrofluoric acid (chemical formula: HF)
- Nitrous acid (chemical formula: HNO2)
Is HF a weak acid?
By contrast, although hydrogen fluoride dissolves freely in water, hydrofluoric acid is only a weak acid; it is similar in strength to organic acids like methanoic acid.
What are 2 weak acids?
Examples of Weak Acids
- Formic acid (chemical formula: HCOOH)
- Acetic acid (chemical formula: CH3COOH)
- Benzoic acid (chemical formula: C6H5COOH)
- Oxalic acid (chemical formula: C2H2O4)
- Hydrofluoric acid (chemical formula: HF)
- Nitrous acid (chemical formula: HNO2)
- Sulfurous acid (chemical formula: H2SO3)
Is NH3 a weak acid?
As it happens, ammonia (NH3) is not a strong acid; it is a weak base. The nitrogen of ammonia is surrounded by four pairs of electrons.
Which are weak acids?
Weak acids are much more common than strong acids. They are found in daily life in vinegar (acetic acid) and lemon juice (citric acid), for example….Examples of Weak Acids.
| Common Weak Acids | |
|---|---|
| acetic acid (ethanoic acid) | CH3COOH |
| formic acid | HCOOH |
| hydrocyanic acid | HCN |
| hydrofluoric acid | HF |
What acids are weak?
Is hydrochloride a weak acid?
When HCl molecules dissolve they dissociate into H+ ions and Cl- ions. HCl is a strong acid because it dissociates almost completely.
