JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
The overall stability constant of the complex ion \(\left[\mathrm{Cu}\left(\mathrm{NH}_{3}\right)_{4}\right]^{2+}\) is \(2.1 \times 10^{13} . \quad\) The overall dissociations constant is \(\mathrm{y} \times 10^{-14}\). Then y is ....... .(Nearest integer)
- A \(50\)
- B \(5\)
- C \(500\)
- D \(1\)
Answer & Solution
Correct Answer
(B) \(5\)
Step-by-step Solution
Detailed explanation
\(\text { Given } \mathrm{k}_{\mathrm{f}}=2.1 \times 10^{13}\) \(\mathrm{~K}_{\mathrm{d}}=\frac{1}{\mathrm{k}_{\mathrm{f}}}=4.7 \times 10^{-14}\) \(\therefore \mathrm{y}=4.7 \approx 5\)
