Describe reaction of group IV elements with water

Reaction of group (IV) elements with water

Carbon does not react with cold water but reacts with steam to form water gas

C(s) + H₂O(g)   →   CO(g) + H₂(g)

Silicon, germanium and Tin do not react with water up to 100⁰C because they are protected by thin layer of oxide. But they react with steam at very high temperatures to form dioxides

Ge(s) + 2H₂O(g) →   GeO₂(s) +2H₂(g)

Lead reacts with soft water (water that contains oxygen) to form lead II hydroxide.

Pb(s) + 2H₂O(g) + O₂(g) → Pb(OH)₂(s)
