Question
What happens when the elements of groups 13, 14 and 15 react with water?
✓
Answer
i. Most of the elements of groups 13, 14 and 15 are unaffected by water.
ii. Aluminium reacts with water on heating and forms hydroxide while tin reacts with steam to form oxide.
a. $\quad 2 Al _{( s )}+6 H _2 O _{(l)} \xrightarrow{\Delta} 2 Al ( OH )_{3( s )}+3 H _{2( g )}$
b. $\quad Sn _{( s )}+2 H _2 O _{( g )} \xrightarrow{\Delta} SnO _{2( s )}+2 H _{2( g )}$
iii. Lead is unaffected by water due to the formation of a protective film of oxide.
