Question

State one industrial application of reduction

Answer 1

Explanation:

Reduction is used in the industries which extract - metal ores for obtaining metal ores.

Some of the applications of reduction in industries are as follows:

• Reduction of the calcium carbonate $(CaCO_3)$ into CaO and $CO_2$.
• Reduction reactions in batteries and cells.  

For example, consider the equation which is given below:

$\mathrm{Zn}+2 \mathrm{MnO}_{2}+2 \mathrm{NH}^{4+} \rightarrow \mathrm{Zn}^{2+}+\mathrm{Mn}_{2} \mathrm{O}_{3}+2 \mathrm{NH}_{3}+\mathrm{H}_{2} \mathrm{O}$

Here, the zinc case is acting as the anode while the reduction of $MnO_2$ takes place.
