Question

Identify the process to which the following reaction belongs :

${A l}_{2} O_{3} . {2 H}_{2} O + {N a}_{2} {C O}_{3} ⟶ {2 N a A l O}_{2} + {2 H}_{2} O + {C O}_{2}$

${2 N a A l O}_{2} + {2 H}_{2} O + {C O}_{2} 50 - 60^{o} C - ------ \to {A l}_{2} O_{3} . {2 H}_{2} O + {N a}_{2} {C O}_{3}$

Solution

The correct option is B Hall's process
Hall's Process: (Red bauxite)
Bauxite one + $N a_{2} C O_{3} F u s e d - -- \to N a A l O_{2}$
$↓$ extracted with water
Solution
$↓$ warmed $50^{o} - 60^{o} C$
$C O_{2}$ is circulated
$↓$
$A l (O H)_{3} + N a_{2} C O_{3}$
