According to the Arrhenius Acid-Base Theory, acids are those substances that dissolved in water divide by generating H⁺ together with an anion (ion with a negative charge). In an aqueous solution, the H⁺ protons react immediately with the water molecules to form H₃O⁺ hydronium ions.
According to this theory, those acids that dissociate completely are strong acids (releasing all protons H⁺), while acids that do not dissociate completely are weak acids (the percentage of dissociation is not 100%, releasing few protons H⁺)
An example is:
HCl + H₂O ⇒ Cl⁻ + H₃O⁺
This is an example of a strong acid.
Half-life is the time it takes for a substance to lose half of its pharmacological, physiological, or radiological activity.
