$AlCl_3 + NaOH \longrightarrow$

Vedclass · Answer

(A) $1$. $AlCl_3 + 4NaOH \longrightarrow NaAlO_2 + 3NaCl + 2H_2O$. This reaction forms aqueous sodium meta-aluminate and does not release any gas. $2$. $3NaOH + P_4 + 3H_2O \longrightarrow PH_3 (	ext{gas}) + 3NaH_2PO_2$. This releases phosphine gas. $3$. $2Al + 2NaOH + 2H_2O \xrightarrow{\Delta} 2NaAlO_2 + 3H_2 (	ext{gas})$. This releases hydrogen gas. $4$. $Zn + 2NaOH \xrightarrow{\Delta} Na_2ZnO_2 + H_2 (	ext{gas})$. This releases hydrogen gas. Therefore,the reaction between $AlCl_3$ and $NaOH$ does not liberate a gaseous product.

Which of the following reactions does not liberate a gaseous product?
