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.
uf076 Reaction on anode region :
Fe (*) → Fe2+ (aq) + 2e-
uf076 Reaction on anode region :
O2 (g) + 4H+ (aq) +................. → 2H2O((l)
When Fe2+ ions migrate from anode region they react with.......... to form Fe3+
A reddish **** hydrated oxide is formed from............. ions. It is called rust
2Fe3+ (aq) + 4H2 O(l) → ............... + 6H+ (aq)
A way to prevent rusting ..................................
