Prolonged heating of ferrous ammonium sulphate is avoided to prevent :

Answer 1

Solution

Prolonged heating of ferrous ammonium sulfate is avoided to prevent oxidation.
Ferrous ammonium sulfate is a green crystalline solid that is used as a reducing agent in various chemical reactions. When heated, it can undergo oxidation to form ferric ammonium sulfate. This is because heating provides energy that can be used to overcome the activation energy required for the oxidation reaction to occur.
The oxidation of ferrous ammonium sulfate can be represented by the following chemical equation:
4FeSO4.(NH4)2SO4.6H2O + O2 → 2Fe2(SO4)3.(NH4)2SO4 + 12H2O
This reaction is exothermic and releases a large amount of heat. Therefore, prolonged heating can provide the energy required to drive the reaction forward, leading to the formation of ferric ammonium sulfate.
To prevent this oxidation reaction from occurring, prolonged heating of ferrous ammonium sulfate is avoided.
