Which of the following reactions is an example of a metal displacement redox reaction? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

A metal displacement reaction involves a more reactive metal displacing a less reactive metal from its compound. In option D, elemental Al (O.S. = 0) displaces Cr (+3) to yield elemental Cr (0) and $Al_2O_3$ (+3).
