Question

write an activity to show redox reaction​

Answer 1

Answer:

Redox Reaction Example

In a redox reaction, the reactant that loses electrons (is oxidized) causes a reduction and is called a reducing agent.

In the example above, zinc metal is the reducing agent; it loses two electrons (is oxidized) and becomes Zn2+ ion.

${\bold{\underline{\underline{ Experiment \::}}}}$

To determine Redox Reactions

${\bold{\underline{{ Purpose \: of \: Experiment \: :}}}}$

• To explore the relative oxidizing and reducing strengths of different metals.

• To gain practice working with electrochemical cells.

• To use experimentally determined cell potentials to rank reduction half-reactions.

${\bold{\underline{{ Materials \: Required \: :}}}}$

Beakers, 4 Glasses, Copper II Sulphate, Sodium Chloride, 4 Different Metals like Zn, Al, Fe , Hg , Spatula.

${\bold{{\underline{ Procedure \: of \: Experiment \: :}}}}$

• Get a 250 ml beaker and filled it with CuSO4 Solution.

• Add some NaCl using Spatula, it increases the rate of reaction.

• Stir beaker for about 2 - 5 minutes and then left it for 2 minutes.

• Get 4 Glasses and filled them with prepared Solution.

• Dip these Metals Samples in those 4 glases one by one.

• After 30 minutes you will see glass contaning Zn will start Redox Reaction.

${\bold{\underline{{ Conclusion \: of \: Experiment \: :}}}}$

In a redox reaction, the reactant that loses electrons (is oxidized) causes a reduction and is called a reducing agent.

In the example above, zinc metal is the reducing agent; it loses two electrons (is oxidized) and becomes Zn2+ ion.
