Question

Write True or False for the following statement

In a metal displacement reaction the more reactive metal acts as a reducing agent.

• A. True
• B. False

Answer 1

The correct option is A True

• In a metal displacement reaction, the more reactive metals displace the less reactive metals from their oxide.
• Thus, the more reactive metal will act as a reducing agent.
• For example, the more reactive metal Magnesium displaces the less reactive metal Copper in the following reaction.
• Magnesium is placed before Copper in the reactivity series therefore it displaces Copper from Copper oxide. $\underset{\left(\mathrm{Copper}\mathrm{oxide}\right)}{\mathrm{CuO}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Magnesium}\right)}{\mathrm{Mg}\left(\mathrm{s}\right)}\stackrel{\mathrm{Heat}}{\to }\underset{\left(\mathrm{Copper}\right)}{\mathrm{Cu}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Magnesium}\mathrm{oxide}\right)}{\mathrm{MgO}\left(\mathrm{s}\right)}$

Hence, the given statement “ In a metal displacement reaction the more reactive metal acts as a reducing agent” is True.
