Statement 1:Na2ZnO2 is water soluble whereas Zn(OH)2 is insoluble Statement 2: Addition of NaOH solution to ZnCl2 gives white ppt. which dissolves on further addition of NaOH due to the formation of complex cation

Question

Statement 1:Na2ZnO2 is water soluble whereas Zn(OH)2 is insoluble Statement 2: Addition of NaOH solution to ZnCl2 gives white ppt. which dissolves on further addition of NaOH due to the formation of complex cation (A) If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1 (B) Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1 (C) If Statement 1 is true but Statement 2 is false (D) If Statement 1 is false but Statement 2 is true

ZnCl2+2NaOH → Zn(OH)2+2NaCl Zn(OH)2+2NaOH → Na2[ZnO2+2H2O [Zn2O]2- is a complex anion

Q. Statement 1: $N a_{2} Z n O_{2}$ is water soluble whereas $Z n (O H)_{2}$ is insoluble
Statement 2: Addition of $N a O H$ solution to $Z n C l_{2}$ gives white ppt. which dissolves on further addition of $N a O H$ due to the formation of complex cation

If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1

Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1

If Statement 1 is true but Statement 2 is false

If Statement 1 is false but Statement 2 is true

$Z n C l_{2} + 2 N a O H \to Z n (O H)_{2} + 2 N a Cl$
$Z n (O H)_{2} + 2 N a O H \to N a_{2} [Z n O_{2} + 2 H_{2} O [Z n_{2} O]^{2 -}$ is a complex anion
