1.	How would you explain the following observations ? Lil is more soluble than Ki in ethanol.
Answer» Solution : Lil is more soluble than KI in ethanol. As a result of its small size, the lithium ion has a higher polarising power than the potassium ion. It POLARISES the electron cloud of the iodide ion to a MUCH GREATER EXTENT than the potassium ion. This causes a greater covalent character in LiI than in KI. Hence, Lil is more soluble in ethanol.
