The following substances dissolve when added to water. Ethanol (ethyl alcohol, C2H5OH) dissolves in water because the partial charges on the H and O atoms in the molecule interacts strongly with the partial charges on the atoms in water. In this case, we start with sodium hydroxide already dissolved in water (note that there are 5 sodium ions and 5 hydroxide ions.In the vapor above, we have introduced 4 hydrogen chloride "molecules".As in the earlier example of hydrogen chloride gas dissolving, when the gas molecules strike the water they dissolve and separate into hydrogen (or hydronium) ions and chloride ions. Nice work! It's a colourless, white liquid with a pung-to-faint ammonia scent. wt. For alcohols with longer chains of carbon atoms, like CH3(CH2)9OH (Decanol) much of the molecule is nonpolar (or only very slightly polar) and the molecule will therefore be insoluble in water.
