Pre-Research (Carisa Chan)

 Here is my research for the keywords below.

partition coefficient: the equilibrium distribution of an analyte between the sample phase and the gas phase.

analyte: the sample being analyzed


solubility: the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvet


hydrophobic: A hydrophobic molecule is repelled by water; literally, hydrophobe means something with a fear of water. Hydrophobic molecules often cluster together when dropped in water, just as oil does. Hydrophobic molecules are also called lipophilic because they will dissolve in oils and other lipids. They tend to be electrically neutral and nonpolar and work better with neutral and nonpolar solvents.


hydrophilic: Hydrophilic literally translates as "water loving" or "water friend." Hydrophilic substances are attracted to, and dissolve well within, water. Hydrophilic is typically used to describe a property of a molecule, and refers to the likelihood of its bonding with the hydrogen molecule in water. A hydrophilic molecule is not just soluble in water but also in other polar solvents; it will dissolve less readily in oils and other hydrophobic solvents. Hydrophilic molecules are charge-polarized so that one end is positive and the other negative.
