Q. Which one among the folloing alkali metal has the highest reducing power ?
- Na
- K
- Li
- Rb
Q. Li has the maximum value of ionisation potential among alkali metals i.e. Lithium has the minimum tendency to ionise to give Li+ ion. Thus, lithium is

- Strongest oxidising agent
- Poorest oxidising agent
- Strongest reducing agent
Q.
The reducing power of a metal depends on various factor. Suggest the factor which makes Li, the strongest reducing agent in aquous solution.
