A) \[Al,AlC{{l}_{3}},NaAl{{O}_{2}}\]
B) \[Zn,\text{ }N{{a}_{2}}Zn{{O}_{2}},\text{ }Al{{(OH)}_{3}}\]
C) \[Al,Al{{(OH)}_{3}},AlC{{l}_{3}}\]
D) \[Al,NaAl{{O}_{2}},Al{{(OH)}_{3}}\]
Correct Answer: D
Solution :
The reactions are as follows: \[\underset{(X)}{\mathop{2Al}}\,+2NaOH+2{{H}_{2}}O\xrightarrow{{}}\underset{(Y)}{\mathop{2NaAl{{O}_{2}}}}\,\]\[+3{{H}_{2}}\uparrow \] \[2NaAl{{O}_{2}}+C{{O}_{2}}+3{{H}_{2}}O\xrightarrow{\Delta }N{{a}_{2}}C{{O}_{3}}\]\[+2Al{{(OH)}_{3}}(Z)\] \[2Al{{(OH)}_{3}}\xrightarrow{1200\,{{\,}^{o}}C}A{{l}_{2}}{{O}_{3}}+3{{H}_{2}}O\]You need to login to perform this action.
