Solubility. The small alcohols are completely soluble in water. If they are mixed with water, there will be one solution. However, solubility falls as the length of the hydrocarbon chain in the alcohol increases. The hydrocarbon chains are forcing their way between water molecules and so breaking hydrogen bonds between those water molecules.

Acidic Properties of Alcohols. Alcohols, like water, are both weak bases and weak acids. In aqueous solutions, alcohols dissociate slightly by donating a hydrogen to water. This creates the alcohol's conjugate base, called an alkoxide ion (RO - ), along with hydronium (H 3 O + ).
Special note: The following electrolytes are of only moderate solubility in water: CH 3 COOAg, Ag 2 SO 4, KClO 4. They will precipitate only if rather concentrated solutions are used. As an example on how to use the solubility rules, predict if a precipitate will form when solutions of cesium bromide and lead (II) nitrate are mixed.
Solubility is often expressed as the mass of solute per volume (g/L) or mass of solute per mass of solvent (g/g), or as the moles of solute per volume (mol/L). Even for very soluble substances, however, there is usually a limit to how much solute can dissolve in a given quantity of solvent.
Los éteres se obtienen a partir de alcoholes mediante la eliminación de una molécula de agua a partir de dos moléculas del alcohol. Por ejemplo, cuando el etanol se trata con una cantidad limitada de ácido sulfúrico y se calienta a 140 °C, se forma éter dietílico y agua:
Se dice que dos líquidos, como el bromo y el agua, que tienen una solubilidad mutua moderada son parcialmente miscibles. Dos líquidos parcialmente miscibles suelen formar dos capas al mezclarse. En el caso de la mezcla de bromo y agua, la capa superior es agua, saturada de bromo, y la capa inferior es bromo saturado de agua.
