Question

Refer to the periodic table and write three metals that can show disproportionation reaction.

Answer 1

Disproportionation is a redox reaction, where a molecule is transformed into two or more dissimilar products. In a redox reaction, the species is simultaneously oxidized and reduced to form at least two different products.

Copper, gallium and indium are the metals that show disproportionation reaction.

The reactions are shown below.

$2C{u}^{+}\to C{u}^{2+}+Cu$
$3G{a}^{+}\to G{a}^{3+}+2Ga$

$3In+\to I{n}^{3+}+2In$
