Question

The value of 'n' in \([ \text{P(O}_3\text{)}_4 ]^{6-}\) is ............
 

Hint:

For polyatomic ions, count the charge on the central atom and surrounding groups to determine oxidation states.

Answer 1

Correct Answer: 6

Step 1: Analyzing the structure.
The species \( [ \text{P(O}_3\text{)}_4 ]^{6-} \) indicates that the phosphorus is surrounded by four \( \text{O}_3 \) groups. The overall charge on the complex is \( 6- \), and phosphorus typically has a formal oxidation state of \( +5 \).

Step 2: Conclusion.
The value of \( n \) in this case is \( \boxed{5} \).
