Question
On passing CO2 into aqueous solution containing Al3+ :
Options
A.Al2(CO3)3 is formed
B.Al(OH)3 is precipitated
C.Al2O3 is formed
D.collodial Al(OH)3 is formed
Solution
CO2 + H2O → H2CO3 ⇋ CO32- + 2H+
3CO32- + 3H2O + 2Al3+ → 2Al(OH)3 ↓ (as weakly acidic) + 3CO2.
3CO32- + 3H2O + 2Al3+ → 2Al(OH)3 ↓ (as weakly acidic) + 3CO2.
