Tardigrade Admin · Accepted Answer

Fe(OH)3 ferric hydroxide is not soluble in NaOH Zn(OH)2+2NaOH xrightarrowNa2ZnO3+2H2O Al(OH)3+NaOH xrightarrowNaAlO2+2H2O Sn(OH)2+2NaOH xrightarrowNa2SnO2+2H2O

Q. Which of the following is not soluble in $N a O H$ ?

$F e (O H)_{3}$

$Z n (O H)_{2}$

$A l (O H)_{3}$

$S n (O H)_{2}$

$F e (O H)_{3}$ ferric hydroxide is not soluble in $N a O H$ $Z n (O H)_{2} + 2 N a O H N a_{2} Z n O_{3} + 2 H_{2} O$ $A l (O H)_{3} + N a O H N a A l O_{2} + 2 H_{2} O$ $S n (O H)_{2} + 2 N a O H N a_{2} S n O_{2} + 2 H_{2} O$
