Colour of the solution when reacts with is:
Colour of the solution when \( K I \) reacts with \( B r_{2} \) is:
- A. pale yellow
- B. reddish-brown
- C. black
- D. none of the above
Step-by-step solution
The reaction of KI (potassium iodide) with Br2 (bromine) produces I2 (iodine) via the redox reaction: 2KI + Br2 → 2KBr + I2. Iodine in aqueous solution appears reddish-brown, so the solution color is reddish-brown.
