Bleaching with Sodium Hypochlorite

NaClO + dye → NaCl + oxidized dye

Visão geral

Sodium hypochlorite (bleach) oxidizes colored organic molecules by breaking the conjugated double bond systems (chromophores) that absorb visible light. The hypochlorite ion (ClO⁻) acts as the oxidizing agent, being reduced to chloride (Cl⁻). This destroys the molecule's ability to absorb colored light.
