What is observed after about I hour of adding strips of Cu and Al suspended in `FeSO_(4)` solution in two beakers. Name the reaction and change observed. Also write the chemical equations.

Text Solution

Verified by Experts

When `Cu` strip is suspended in `FeSO_(4)` solution, no reaction takes place. When Al strip is suspended in `FeSO_(4)` solution the pale green colour becomes colourless and grayish black iron metal will deposit on aluminium strip
`2Al(s)+3FeSO_(4)(aq)toAl_(2)(SO_(4))_(3)(aq)+3Fe(s)`.
