Some people get around this problem, by using a water softener which removes the ions in the water by replacing them with sodium ions (Na+). The ancient Roman tradition called for mixing rain water, potash and animal tallow (rendered form of beef or mutton fat). Explain how the bromine test works to detect unsaturation. One the above structure, circle the portion of the molecule that is water-soluble. 5. Wash your hands with a small sample of finished olive oil soap. In this lab, you will test various fats and oils for their degree of saturation by reacting any double bonds in the fat or oil with bromine. This will serve as a hardener for the liquid soap.

Additionally, you will explore water that has a high concentration of dissolved minerals which is called hard water. A faint Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions). In John Singer Sargent's famous Portrait of Madame X, for example, the lumps only appear on the blackest areas, which may be because of the artist's use of more medium in those areas to compensate for the tendency of black pigments to soak it up. Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions).
