### Iodometric determination of copper and iron in one solution

Copper is titrated first, iron being masked with fluoride. After the endpoint is reached, aluminium chloride is added to demask the iron, which is titrated after some minutes. Good results are obtained. INTRODUCTION THE iodometric determination of copper11 in the presence of iron111 is usually performed in weakly acid medium.

### Iodometric titration of copper Titration and titrimetric

Iodometric determination of copper is based on the oxidation of iodides to iodine by copper (II) ions, which get reduced to Cu +. Comparison of standard potentials for both half reactions (Cu 2+ /Cu + E 0 =0.17 V, I 2 /I E 0 =0.54 V) suggests that it is iodine that should be acting as oxidizer.
