What is most Lily true about the attractive forces between ions in a compound that is very soluble in water compared to a compound that is relatively insoluble in water?

Opposite poles of attract each other and make bonds.

Explanation:

Those compounds are soluble in water which have polar nature means that make poles with other atoms while on the other hand, those compounds which doesn't have polar nature are dissolve in non-polar solvent. The polar nature of compounds is due to their difference in electronegativities so in polar compounds opposite poles attract one another and make bonding with each other.

they are all solids.
