S1: AgI is less soluble in water than AgF due to more polarisation of I- in comparison to F– ion.
S2: Melting point of BaCl2 is higher than the melting point of BeCl2 due to greater ionic nature of BaCl2.
S3: Order of hydrated radii is : Al3+ (aq) > Mg2+ (aq) > Na+ (aq)

Answer
T TT
Explanation
Solution
AgI is less soluble than AgF due to covalent nature. LiI is more soluble then LiF due to high size difference of ions more ionic nature, more melting point. Higher the charge density , larger will be the hydrated radii.
