I was also confused at this same problem, but what I found out is that there are 2 possible explanations for this conundrum:
Entropy causes everything to become more disordered, and so ionic compounds will dissolve to increase entropy.
Each ion can participate in multiple ion-dipole interactions when dissolved, and these multiple ion-dipole interactions ...

The bond length, intermolecular forces, and molecular shape all determine the lattice structure, which in turn determines the density of the substance. Thus, with a small enough bond length, solids can be more dense than liquids due to a much more tight lattice structure.
Water is somewhat unique in its densities due to its bent molecular geometry. Most ...

Here is a sketch of a layer of ice:
The hydrogen bonds are fairly short (177 pm, compared to a covalent O-H bond length of 100 pm), and the distance between hydrogen-bonded atoms is shorter than the minimal distance in the absence of the hydrogen bond (about 195 pm).
What should be apparent from the image is that there is a lot of space in the center of the ...

Which of these functional groups is soluble in aqueous HCl and/or NaOH?
Functional groups don't have solubility. Their presence in a compound, however, can have an effect on solubility.
My approach before was this : Esters do not dissolve in cold aqueous bases or acids, nor do amides or alcohols. Amines dissolve in aqueous acids. Phenols and Carboxylic ...
