The solubility order of the chlorides of the alkali
metals is
(1) NaCl > KCI > RbCI > CsCI
(2) CsCl > RbCI > KCI > NaCl
(3) KCI > NaCl > RbCI > CsCI
(4) CsCl > RbCI > NaCl > KCL
​

Answer 1

Answer:

Thus, the lattice enthalpy of ionic solid i.e. alkali metal chloride decreases down the group. - Now, if we combine all these factors, then the solubility of the chlorides of the alkali metal decreases down the group. - Therefore, the order is NaCl > KCl > RbCl > CsCl.
