How does copper sulfate react with luminol
WebThe particularly vigorous chemical luminescence occurring on oxidation of 3-aminophthalic acid hydroazide luminol was discovered by W. Lommel and subsequently investigated in greater detail by several researchers. The oxidizing agent most frequently used was a mixture of sodium hypochlorite and hydrogen peroxide.

WebIn this reaction, a small amount of luminol (3-aminophthalhydrazide or 5-amino-2,3-dihydro- 1,4-phthalazinedione) is dissolved in a basic aqueous solution, which also contains a small amount of copper (II) sulfate. To … WebCopper sulfate is highly soluble in water, with solubility values of 1.055 molal and 1.502 molal ate 10 o C and 30 o C respectively. A typical example of a single displacement reaction where one metal displaces another is …
WebAug 8, 2016 · The catalytic behaviour of the copper in this reaction is immediate and obvious. While the uncatalysed reaction involves direct addition of dissolved oxygen to the luminol molecule, Burdo and colleagues have shown that, at least for the Co(II)-catalysed reaction, the formation of a metal ion–peroxide complex is important.
