The mismatched combinations are \(A.\) Chlorophyll - Co \(B.\) Water hardness - EDTA \(C.\) Photography \(-\left[ Ag ( CN )_2\right]^{-}\) \(D.\) Wilkinson catalyst - \(\left[\left(P h_3 P\right)_3 R h C l\right]\) \(E.\) Chelating ligand - D - Penicillamine Choose the correct answer from the options given below:
- A \(A\) and \(C\) Only
- B \(A\) and \(E\) Only
- C \(D\) and \(E\) Only
- D \(A,C\) and \(E\) Only
Answer & Solution
Correct Answer
(A) \(A\) and \(C\) Only
Step-by-step Solution
Detailed explanation
\(Mg\) is present in chlorophyll and in black and white photography the developed film is fixed by washing with hypo solution which dissolves the undecomposed \(AgBr\) to form a complex ion \(\left[ Ag \left( S _2 O _3\right)_2\right]^{3-}\)
