Due to the effect of the still dissolved soap, the insoluble compounds end up in the foam and build the scum. Soap scum. Soap scum or lime soap is the white solid composed of calcium stearate, magnesium stearate, and similar insoluble compounds that results from the addition of soap and other anionic surfactants to hard water. In this reaction, the sodium cation in soap is replaced by calcium to form calcium stearate. When a soap is used in hard water, a solid substance we call scum forms. This is because charged calcium and magnesium particles (called ions) present in the water react with soap to form an insoluble substance. Scum builds up on clothes, baths and sinks.

Due to the effect of the still dissolved soap, the insoluble compounds end up in the foam and build the scum. Mar 27,  · Most of what soap scum is (and getting rid of it for that matter) is basic chemistry. Soap scum is simply a white solid that is composed of calcium stereate, magnesium stereate, and the waste products that are formed through the addition of soap to hard marinecatering-expo.com: Robert Coleman. When a soap is used in hard water, a solid substance we call scum forms. This is because charged calcium and magnesium particles (called ions) present in the water react with soap to form an insoluble substance. Scum builds up on clothes, baths and sinks. Soap scum is actually what you get when soap combines with minerals in your water which forms a chemical reaction. It is not bacteria or mold but it can be a house for bacteri a to multiply. Perhaps you have on occassion noticed mineral deposits on your cooking dishes, or rings of insoluble soap scum in your bathtub. These are not signs of poor housekeeping, but are rather signs of hard water from the municipal water supply. Hard water is water that contains cations with a charge of +2, especially Ca 2+ and Mg 2+. These ions do not pose any health threat, but they can engage in .Previously, we looked at how detergents function to remove grease and oil when washing dishes. When soap is added to hard water, the calcium ions see the sodium atoms on the end of each soap molecule. In a somewhat bullish fashion, a single calcium ion knocks the sodium off the. Soap scum or lime soap is the white solid composed of calcium stearate, magnesium stearate, Angelo Nora, Alfred Szczepanek, Gunther Koenen ( ), "Metallic Soaps", Ullmann's Encyclopedia of Industrial Chemistry, Weinheim. I want it dead. I want the most aggressive thing I can find that won't eat through my acrylic tub and PVC drain. HCL? Sodium hydroxide?. A soap can simply be shown as a sodium salt of a fatty acid R-COOH + Na+ → RCOONa + H+ The soap is soluble in water A soap scum forms when the sodium . Or, if you want to get into the chemistry of it, the molecules in soap include a “free end” that is attractive to fat molecules. In other words, soap scum is really just a.
