Importance of mossy zinc in the reflux to prepare trisethylenediaminechromium (iii)
Accepted Answer
Mossy zinc is used as a reducing agent in the reflux reaction to prepare trisethylenediaminechromium(III) ([Cr(en)₃]³⁺). It reduces Cr³⁺ ions to Cr²⁺ ions, which then react with ethylenediamine (en) to form the complex. The mossy zinc provides a large surface area for the reaction to occur, increasing the efficiency of the reduction process.
