Question
Water transported through lead pipes becomes poisonous due to the formation of :
Options
A.Pb (OH)2
B.PbO
C.PbO2
D.Pb3O4
Solution
Lead slowly dissolves in water containing dissolved oxygen to form Pb(OH)2 which makes the water poisonous. Dissolution of lead in water is called plumbosolvency.
2Pb + O2 + 2H2O → 2Pb(OH)2
2Pb + O2 + 2H2O → 2Pb(OH)2
