(v) Complete the process of iron rusting by filling the blanks. Suggest a way
to prohibit the process.
The iron rust is formed due to
reaction. Different regions on
iron surface become anode and cathode.
• Reaction on anode region :
Fee
- Fe2+
(aq)
+ 2e -
• Reaction on cathode region :
O2(g) + 4H+ +
(aq)
→ 2H,0a)
When Fe 2+ ions migrate from anode region they react with
form Fe3+ ions.
