The halogen acid with the highest reducing power is:
Correct answer: B. HI
- A. HF
- B. HI
- C. HBr
- D. HCl
Explanation
Reducing power refers to the ability of a substance to reduce another substance by donating electrons. The halogen acids, HF, HCl, HBr, and HI, can all act as reducing agents, but the strength of their reducing power increases as we move down the group. Hence, HI is the halogen acid with the highest reducing power.

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.
