Element ' X ' is forming a complex of the type [XCl(H2O)5]2+.
Total number of ligands attached to X is 6 (one Cl and five H2O ).
∴ Covalency of X is 6 .
Cl is a unidentate ligand with charge −1.
H2O is a unidentate ligand with charge 0 .
∴‌‌x+(−1)+0‌=+2
x−1‌=+2
x=+2+1=‌+3
∴ Oxidation state of x is +3.
