Why suitable reducing agents are required for reduction ofetal oxides?what are the guidelines to choose a particular reducing agent?
Answer: one way to produce pure metals is to recover them from oxides. However, each metal has its own electrode and chemical potentials, which, in principle, are related to each other. In this connection and, on the basis of this, a suitable reducing agent is needed to produce the metal from its oxide. Recommendations for choosing a specific reductant are some patterns that are identified by experience. In particular, there is one main recommendation: the reductant must be selected in such a way that the potential in the oxidation-reduction system is positive.
