Question

Identify substance oxidised, reduced, oxidising agent and reducing agent
(i) 3Fe+4H20 Fe2O3 + 4 H2
(ii) 2H2+O2 → 2H20​

Answer 1

Answer:

$\star$The given chemical equations are redox reactions

{Both Oxidation and reduction takes place in a single reaction}

$\sf (i) 3Fe+4H_2O \implies Fe_2O_3+4H_2O$

$\sf (ii)2H_2+O_2 \implies 2H_2O$

Important Points to remember:

⇒ Oxidation is the loss of electrons during a reaction

⇒ Reduction is the gain of electrons during a reaction

⇒ Molecule which undergoes oxidation is reducing agent

⇒ Molecule which undergoes reduction is oxidizing agent

With this information we can conclude,

In reaction (i)

Fe is reducing agent

H₂O is oxidizing agent

In reaction (ii)

H₂ is reducing agent

O₂ is oxidizing agent
