Bleaching chemistry

WebThe reaction between NaOCl and water produces produces HOCl, or hypochlorous acid, and sodium hydroxide, or caustic soda, as shown in the following chemical equation. NaOCl + H 2 O → HOCl + NaOH. Hypochlorous acid is responsible for bleach's ability to remove colour from objects and for its ability to disinfect surfaces. Colors of natural organic materials typically arise from organic pigments, such as beta carotene. Chemical bleaches work in one of two ways: • An oxidizing bleach works by breaking the chemical bonds that make up the chromophore. This changes the molecule into a different substance that either does not contain a chromophore or contains a chromophore that does not absorb visible light. This is the mechanism of bleaches ba…
