Question:
What is the value of x on the \([Ni(CN)_4]^x\) complex ion?
What is the value of x on the \([Ni(CN)_4]^x\) complex ion?
Show Hint
Always sum metal charge and ligand charges to get overall charge.
Updated On: Apr 16, 2026
- +2
- -2
- 0 (zero)
- +4
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Charge of complex = metal + ligands.
Step 1: Oxidation state of Ni.
Ni = +2
Step 2: Ligand charge.
Each CN = -1, total = -4
Step 3: Total charge.
\[ x = +2 - 4 = -2 \]
Step 1: Oxidation state of Ni.
Ni = +2
Step 2: Ligand charge.
Each CN = -1, total = -4
Step 3: Total charge.
\[ x = +2 - 4 = -2 \]
