Answer 2

Answer:

The ability of a chemical species to cause the reduction of another chemical substance is known as reducing power.

The amount of energy that changes (E) when one electron is added to the outermost shell of an isolated gaseous atom is known as the electron affinity.

Explanation:

In the case of lithium, hydration energy compensates for ionization energy. Lithium thus has the highest oxidation potential and reducing power in aqueous solution among alkali metals.

As the electron gets added to the isolated gaseous atom, it will result in more positive electron affinity.

The given electron affinity order is correct.

The order of oxidation number of oxygen O₃ > KO₂ > BaO₂ > K₂O is correct.

The order of pH of aqueous solution LiCl > BeCl₂ > MgCl₂ < AICI₃ is incorrect because LiCl has a pH of 7 while MgCl₂ has a pH > 7. Thus, this statement is incorrect.

The correct option is (d)  pH of aqueous solution LiCl > BeCl₂ > MgCl₂ < AICI₃.
