In order to concentrate galena (which contains ZnS as impurity) by froth-floatation process, sodium cyanide is used as depressant. NaCN dissolves ZnS due to the formation of the water soluble complex (A). Find the value of w+x+y+z. Where, w= coordination number of the central metal ion in the complex ion of (A). x= number of unpaired electrons in (A). y= total number of possible linkage isomers of (A) including (A). z= maximum number of atoms in a single plane in the complex ion of (A).

1.	In order to concentrate galena (which contains ZnS as impurity) by froth-floatation process, sodium cyanide is used as depressant. NaCN dissolves ZnS due to the formation of the water soluble complex (A). Find the value of w+x+y+z. Where, w= coordination number of the central metal ion in the complex ion of (A). x= number of unpaired electrons in (A). y= total number of possible linkage isomers of (A) including (A). z= maximum number of atoms in a single plane in the complex ion of (A).
Answer» In order to concentrate galena (which contains $Z n S$ as impurity) by froth-floatation process, sodium cyanide is used as depressant. $N a C N$ dissolves $Z n S$ due to the formation of the water soluble complex $(A)$ . Find the value of $w + x + y + z$ . Where, $w =$ coordination number of the central metal ion in the complex ion of $(A)$ . $x =$ number of unpaired electrons in $(A)$ . $y =$ total number of possible linkage isomers of $(A)$ including $(A)$ . $z =$ maximum number of atoms in a single plane in the complex ion of $(A)$ .
