Current Question (ID: 9108)

Question:

$\text{Lithium has the minimum tendency to form } \text{Li}^+ \text{ ion. The aqueous solution of lithium is the:}$

Options:

1. $\text{Strongest reducing agent.}$
2. $\text{Poorest reducing agent.}$
3. $\text{Strongest oxidising agent.}$
4. $\text{Poorest oxidising agent.}$

Solution:

$\text{HINT: The hydration enthalpy of } \text{Li}^+ \text{ is very high.}$ $\text{Explanation:}$ $\text{The ionisation potential value of Lithium is maximum among alkali metals i.e. its tendency to ionise to give } \text{Li}^+ \text{ ions should be the minimum i.e. Li should be the poorest reducing agent.}$ $\text{But, lithium is the strongest reducing agent in aq. solution. This is due to the largest value of hydration energy of } \text{Li}^+ \text{ ions.}$
