Bromine can be liberated from KBr solution by the action of _______________?
Correct answer: B. Chlorine
- A. Iodine solution
- B. Chlorine
- C. NaCl
- D. Ki
Explanation
Chlorine is more reactive than bromine and oxidises bromide ions: Cl2 + 2KBr -> 2KCl + Br2. Iodine is a common wrong choice because it is also a halogen, but iodine is less powerful than bromine and cannot displace it from bromide.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
