Cu2+ react with ki
WebChemical Reactions of Diazonium Salts. Reactions which involve retention of the diazo group. This article deals with the reactions which involve the replacement of nitrogen. Diazonium group is a good leaving group. They are substituted by other groups such as Cl –, Br –, CN –, and OH – which easily displace nitrogen from the aromatic ring. Web2Cu2 + + 4I − ⇌ 2CuI(s) + I2 This is a rapid, quantitative reaction in slightly acidic solutions, if there is a large excess of iodide ion present and if the copper is in the form of a simple ion rather than a complex one. The iodine that is liberated can be titrated in the usual manner with standard thiosulfate solution.
