A) In Baeyer?s process bauxite is digested with\[NaOH\]solution
B) In Hall?s process bauxite is fused with\[N{{a}_{2}}C{{O}_{3}}\]
C) In Serpeck's process bauxite is mixed with coke and heated in an atmosphere of\[C{{O}_{2}}\]
D) Hoope's electrolytic cell is used for the purification of aluminium
Correct Answer: C
Solution :
Sol. In Serpeck's process bauxite is mixed with coke and heated to 2000 K in an atmosphere of\[{{N}_{2}}\]to give\[AlN\]. \[A{{l}_{2}}{{O}_{3}}.2{{H}_{2}}O+{{N}_{2}}+3C\xrightarrow{{}}2AlN+3CO\] \[+2{{H}_{2}}O\]You need to login to perform this action.
