- A \(3\)
- B \(30\)
- C \(12\)
- D \(1\)
Answer & Solution
Correct Answer
(A) \(3\)
Step-by-step Solution
Detailed explanation
\(CoCl _{3} \cdot 4 NH _{3} \rightarrow\left[ Co \left( NH _{3}\right)_{4} Cl _{2}\right] Cl\) \(NiCl _{2} \cdot 6 H _{2} O \rightarrow\left[ Ni \left( H _{2} O \right)_{6}\right] Cl _{2}\) \(PtCl _{4} \cdot 2 HCl \rightarrow H _{2}\left[ PtCl _{6}\right]\)…
