WebThen, excess iodide is added in the form of potassium iodide to promote the solubility of iodine and the formation of the CuI precipitate along with … 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.
WebThe reaction is performed under mildly acidic conditions. Copper cyanide has historically been prepared by treating copper(II) sulfate with sodium cyanide, in this redox reaction, … 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.
