Al(2)O(3)+N(2)+Crarr X+CO, X+H(2)Orarr...

`Al_(2)O_(3)+N_(2)+Crarr X+CO`,
`X+H_(2)Orarr Y+Z`
'Y' is an amphoteric substance. When aqueous 'Z' is treated with `AICI_(3)` solution again 'Y' is formed. What are X, Y and Z? 

Text Solution

Verified by Experts

`X=AIN`, which on hydrolysis gives `Al(OH)_(3)` and ammonia. `Y =Al(OH)_(3) and Z=NH_(3)`
Ammonium chloride precipitates aluminium hydroxide with aqueous ammonia.
`AlCl_(3)+3NH_(4)OH rarr Al(OH)_(3)+3NH_(4)Cl`
