Is bleaching a stain out of a article clothing a chemical change or a physical change?
Bleaching is done by oxidising chemicals like hypochlorite (bleaching powder) or peroxides. So it is a chemical change(called reaction): the stain is not (only) dissolved, but (rather) broken down to colorless molecules.Additions to this answer are on the discussion area.
What evidence of chemical reaction when bleaching a stain?
For most kinds of bleach, it is Redox (Oxi-Reduction). Traditional bleach is mainly composed of molecules with chlorine, which is what bleaches the stains. When something is bleached it is because the chlorine is reacting with the substance in the stain. Since the chlorine ions are Cl-, they have extra electrons and donate them to the molecules of the stain: this is reduction of the molecules of the stain. The chlorine loses an electron exactly because it donated it to that molecule: this is oxidation of the chlorine ions. Hence Oxidation-Reduction, Oxi-Reduction, Redox.
When a substance dissolves it leaves a stain which in science is called what?
A stain? Could be a salt: an ionic compound formed from the reaction between an acid and a base.
