A) \[A{{l}^{3+}}\] and \[S{{n}^{2+}}\]
B) \[A{{l}^{3+}}\] and \[F{{e}^{3+}}\]
C) \[A{{l}^{3+}}\] and \[Z{{n}^{2+}}\]
D) \[Z{{n}^{2+}}\] and \[P{{b}^{2+}}\]
Correct Answer: B
Solution :
\[NaOH+A{{l}^{+3}}\,\to \,\underset{(\text{Soluble}\,\text{in}\,NaOH)}{\mathop{\underset{\text{Sod}\text{. metaaluminate}}{\mathop{NaAl{{O}_{2}}}}\,}}\,\] \[NaOH+F{{e}^{+3}}\,\to \]No reaction (Insoluble in NaOH)You need to login to perform this action.
