Why thiocyanate is used in iodometry of copper

Answers

Answered by TanmayMehta

Iodometric determination of copper is based on the oxidation of iodides to iodine by copper (II) ions, which get reduced to Cu+. ... Copper (I) thiocyanate is slightly less soluble than iodide, which makes concentration of Cu+ even lower, increasing the oxidation potential of the Cu2+/Cu+ system.
