Using Arrhenius’ definition, acids are those that produce the hydrogen ion when dissolved in water ( ) while bases produce the hydroxide ion ( ). These ions, when in water, act as charge carriers and can hence conduct electricity. Stronger acids dissociate completely and produce more of the ions.
Why do strong acids conduct electricity better?
Strong acids completely dissociate into H+ ions and some other (-) charged counter ion. … These ions allow the solution to conduct electricity.
Are strong acids good conductors of electricity?
A strong acid will be a better conductor of electricity than a weak acid at the same concentration and at the same temperature. A strong acid will have a lower pH than a weaker acid at the same concentration and at the same temperature.
How do strong acids carry an electric current?
Strong acids and salts are strong electrolytes because they completely ionize (dissociate or separate) in solution. The ions carry the electric charge through the solution thus creating an electric current.
How do you know if an acid is strong or weak?
Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid.
Is H2SO3 a good conductor of electricity?
➢ Weak Molecular acids (Made of molecules with no charge) are less than 100% ionized so they are Poor Conductors (eg. H2SO3, HNO2, HF, CH3COOH etc.) … are all Good Conductors because they are Soluble.
Is chloric acid strong or 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 is the pH of a weak acid?
The value of pH for a weak acid is less than 7 and not neutral (7). Its pH value is less than that of strong acids. Nonetheless, there can be some exceptions as Hydrofluoric acid’s pH is 3.27, which is also low as strong acid hydrochloric acid with pH value 3.01.
Does acid or base conduct electricity?
If the acid or base conducts electricity strongly, it is a strong acid or base. If the acid or base conducts electricity weakly, it is a weak acid or base.

What are strong acids examples?
Examples of Strong Acids
- Hydroiodic 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.
Can alkali conduct electricity?
Acidic and alkaline solutions can conduct electricity because they have ions that are free to carry charge.
