Vedclass · Answer

(B) $1$. $Li$ is the strongest reducing agent in aqueous solution due to its high hydration energy.$2$. The density of alkali metals generally increases down the group,but $K$ is an exception because it has a larger atomic volume than $Na$,making its density $(0.86 \ g/cm^3)$ lower than that of $Na$ $(0.97 \ g/cm^3)$. Thus,the statement that the density of $K$ is greater than $Na$ is false.$3$. $Li^+$ has the smallest ionic radius in the gas phase,but in aqueous solution,it has the largest hydrated ionic radius due to extensive hydration.$4$. All alkali metals dissolve in liquid ammonia to form deep blue,conducting,and paramagnetic solutions due to the presence of ammoniated electrons.
