process is the extraction of an aqueous solution with an organic solvent. Diethylether‚ toluene‚ and hexane are common solvents that are immiscible with and less dense than water. They form a separate phase that floats on top of the aqueous phase. Chloroform and carbon tetrachloride are common solvents that are denser than water. In the two-phase mixture‚ one phase is mostly water and the other phase is mostly organic because they are immiscible liquids. Two liquids are miscible if they form a single

Table A2 further validates the relationship between mass and frequency. Deuterated chloroform has a higher mass than water since deuterium is heavier than hydrogen. Since that is the case it makes sense that hydrogen had a
