Acids and bases are classified as strong or weak based on their ability to dissociate in water. A strong acid or base dissociates completely into ions in water, while a weak acid or base only partially dissociates. This is determined by the equilibrium constant for dissociation reactions.
A weak acid partially dissociates in water, meaning it does not completely break apart into ions. This results in lower concentration of hydrogen ions in solution compared to a strong acid, which completely dissociates to release more hydrogen ions. Weak acids have a higher pH value compared to strong acids.
An acid that dissociates completely in water is called a strong acid. This means that it fully ionizes into its constituent ions in solution, leading to a high concentration of hydronium ions (H3O+). Strong acids have a high affinity for donating protons to water molecules.
Hydrochloric acid (HCl) is a strong acid because it completely dissociates in water, producing a high concentration of H+ ions. Sulfuric acid (H2SO4) is a strong acid because it is a strong electrolyte, meaning it fully dissociates into H+ and HSO4- ions in solution.
Potassium phosphate (K3PO4) is a strong base. It completely dissociates in water to release hydroxide ions, which can accept protons from acids, resulting in a basic solution.

Weak acids do not completely dissociate in water, meaning they only partially ionize. This results in a lower concentration of hydronium ions compared to a strong acid at the same concentration. Additionally, weak acids have higher pKa values compared to strong acids.
Sulfuric acid is a strong acid because it completely dissociates in water to form hydrogen ions (H+) and sulfate ions (SO4^2-). This high degree of dissociation results in a high concentration of hydrogen ions in solution, making sulfuric acid a strong electrolyte and a strong acid.
It dissociates (or ionizes) nearly completely with water.
strong acids dissociate completely into ions in water. i.e. HCl dissociates into H+ and Cl- ions. Weak acids only dissociate partially, therefore they are in an equilibrium state where there is some acid remaining and some ions in solution.
Hydrochloric acid (HCl) ionizes completely in solution and is considered to be a strong acid. It dissociates into hydrogen ions (H+) and chloride ions (Cl-) when dissolved in water.
A strong base completely dissociates to produce hydroxide (OH-) ions in water.
