Importance of mossy zinc in the reflux to prepare tris(ethylenediamine)chromium (iii)
Accepted Answer
Mossy zinc is often used as a reducing agent in the preparation of tris(ethylenediamine)chromium(III) ([Cr(en)₃]³⁺). It helps to reduce Cr(III) to Cr(II) which is a key step in the synthesis. The reaction occurs in acidic conditions and is often carried out under reflux conditions to ensure complete reduction.
