  • Disadvantages Of Lipid Soap

    883 Words  | 4 Pages

    Lipids are organic molecules that are insoluble in water and can be classified into two major types: one which contains ester linkage and one which does not. Lipids that contain ester linkage like fat and wax can be easily hydrolysed, whereas lipids without ester linkage like cholesterol cannot be hydrolysed. Because of the various characteristics of lipid, it can be used in producing many products. Soap is a form of lipid, by mixing various fat and oils with sodium hydroxide. A soap molecule consists

  • Saponification Process Of Soap

    750 Words  | 3 Pages

    The saponification (a reaction in making soap) process is a base (usually NaOH or KOH) hydrolysis of triglycerides to make salt (soap) and glycerol. Alkalis such as Sodium carbonate and Sodium hydroxide are used to neutralize the fatty acid and convert it to a salt. The molecules crystallize differently depending on the base used. NaOH produces a harder bar while KOH is used more frequently for liquid soaps. In some cases, Lithium soaps are formed and produce much harder soaps. There are four

    One of the most serious problems faced by the Earth is the depletion of ozone layer. It is also one of the reasons that cause global warming. The ozone is a colourless gas that found in the stratosphere of the upper atmosphere. The ozone layer is about 17-25 kilometers above the Earth. The layer of ozone gas is a layer which protects us from the ultraviolet radiations which is harmful from the sun. The ozone layer contains high concentrations of ozone molecules (O3) that absorb ultraviolet (UV) radiation

    Ozone depletion is a man made phenomena which industries release CFC (chlorofluorocarbons), rising up to the upper atmosphere exposing to high energy UV radiation from the Sun. Even though that CFC has low reactivity, flammability and toxicity, it remains inert in the troposphere as they disseminate among the stratosphere whereas the UV rays strikes the CFCs molecules and releases chlorine. The chemical reacts with ozone (O3/oxygen), a natural combination of O2 (oxygen) molecules and free oxygen

    Catalysts are substances that cause the acceleration of a chemical reaction, therefore increasing the rate of a chemical reaction, without itself being affected or undergoing any permanent chemical change. Catalysts increase reaction rate by lowering the amount of activation energy needed, meaning that particles can collide with less energy, this results in more particles successfully and effectively colliding. Catalysts don’t get used up in chemical reactions, and therefore can be used repeatedly
