What is Weak Acid?
Weak Acid are those acid which dissociates partially in aqueous solution. They dissociates partially in cation and anion when dissolved in aqueous solution.
- They do not loose H+ ion easily in aqueous solution.
- Weak acid has higher pH as compared to Strong acid because they do not dissociate easily into their ions in aqueous solution.
- Weak acids are bad conductor of electricity in aqueous solution.
Weak Acid Definition
Weak Acids are defined as the acids which partially dissociates into H+ and OH– ion in water
Dissociation of Weak Acids
Weak Acids dissociates partially in aqueous solution while Strong Acids dissociates completely in aqueous solution. The strength of acids depend upon how much it dissociates in aqueous solution. The dissociation of a weak acid can be expressed as follows:
HA⇌ H+ + OH–
where,
- HA represents the weak acid molecule.
- H+ represents a hydrogen ion (proton).
- OH– represents the conjugate base of the weak acid
Strong and Weak Acids
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.
