Cu2+ react with ki
WebJun 15, 2016 · I thought of this reaction: C u X 2 + + 2 K I C u I X 2 + 2 K X +. But since C u I X 2 doesn't exist, the I X − ions must reduce C u X 2 + to C u I and simultaneously get oxidised to I X 2 and thus it will proceed the following reaction:-. 2 C u X 2 + + 4 K I 2 C u … 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. WebThis was followed by the addition of excess KI producing I2 and CuI precipitate from Cu 2+ (Reaction 1). Then, the liberated I2 reacted with the excess KI forming triiodide anion (Reaction 2), which was then titrated with Na 2 S 2 O 3 titrant (Reaction 3). This entire solution required 17.60 mL of the titrant to reach the starch end point.
