I2(aq) + 2S2O32-(aq) â 2I-(aq) + S4O62-(aq). The copper(II) ions can also be titrated against a solution of EDTA in a complexiometric titration. The indicator to use is called Fast Sulphon F. An acid-base titration would not at first sight seem to be very helpful.he blue colour of your solution is caused by the Cu2+(aq) ion. The more concentrated the solution the more intense the colour is. You can make up known concentrations of copper(ll) ion solution and use a colorimeter to produce a copper(ll) ion concentration/absorbance calibration curve.
EDTA is also used intramuscularly for lead poisoning and related brain damage. EDTA is sometimes used as an ointment for skin irritations produced by metals such as chromium, nickel, and copper. Eye drops containing EDTA are used to treat calcium deposits in the eye. In foods, EDTA bound to iron is used to fortify grain-based products such as breakfast cereals and cereal bars.
