  there is no such thing as lye free soap Many solids and gases dissolve in water. As you increase the temperature, you can dissolve more solid. Does this work the same with gas?. NO – as you increase temp, gas molecules KE !. Where can you go to find if something is soluble or insoluble in water?.
