Let’s write down the reactions for the next chain of compounds.
Fe – FeCl₂ – FeСl₃ – Fe (OH) ₃ – Fe₂O₃ – Fe (NO₃) ₃.
1. Substitution reaction.
Fe + 2HCl = FeCl₂ + H₂.
As a result, ferric chloryl is formed and hydrogen is evolved.
2. The reaction of the connection.
2FeCl₂ + Cl₂ = 2FeCl₃.
Formed ferric chloride.
3. Reaction of exchange.
FeCl₃ + 3NaOH = Fe (OH) ₃ + 3NaCL.
As a result, iron hydroxide and sodium chloride are formed.
4. Decomposition reaction.
2Fe (OH) ₃ = Fe₂O₃ + 3H₂O.
Compounds of iron oxide and water are formed.
5. Reaction of exchange.
Fe₂O₃ + 6HNO₃ = 2Fe (NO₃) ₃ + 3H₂O.
Compounds of iron nitrate and water are formed.
