Actually most of the salts are insoluble in water. Not all the salts include chloride!!! And of those witch contain chloride, silver, led and mercury salts are insoluble!!! chemically speaking, not all salts are soluble in a particular solvent under normal conditions..
Dec 8, 2015. Alkanes are not soluble in water. Alkanes are hydrocarbons that aren't very reactive, and are colorless and odorless. They are insoluble in water because the Van Der Waal forces between alkanes and water molecules do not release as much energy as it takes to dissolve hydrogen ions, therefore alkanes don't dissolve in water.
