Correct answer: B. White
- A. Red
- B. White
- C. Brown
- D. Pinkish
Explanation
Silver, in the form of Ag+, despite being a transition element, forms colourless compounds. The reason is, Ag+ has completely filled d orbitals. For transition metal ions to exhibit colour, their metal ions must have incompletely filled (n-1) d orbitals.
