Which of the following compounds in each pairs is more soluble in water
(i) NaCl or LiCl
(ii) NaF or LiF
(iii) Na2CO3 or Li2CO3
(iv) NaOH or LiOH
Dear Student
Due to extremely small size and high charge density of Li, covalent character is induced in the compounds of Li. Therefore Li form covalent compound where as Na due to larger size than Li forms ionic compound.Ionic compound are polar in nature and so dissolve more readily in polar solvents like water hence compounds of Na like NaCl, NaF, Na2CO3 and NaOH will be more soluble in water.
