Iodometric Titration Zinc Ore

This is followed during titration by the reaction of the iodine with the thiosulfate 2S 2 O 3 2 + I 2 → S 4 O 6 2 + 2I sample size. For 0.1 M titrant and assuming 50 mL burette, aliquot taken for titration should contain about 0.22 0.28 g of copper (3.5 4.5 millimoles). end point detection.

    A Rapid Iodometric Method For The Determination Of Copper

    A method has been described for the iodometric simultaneous determination of zinc and copper. Copper is determined in the presence of sufficient KCNS and a small amount of KI. This is followed by the titration of the iodine equivalent to the zinc, which is liberated by the addition of potassium ferricyanide solution.
