  • 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

  • Racemic Mixture Research Paper

    863 Words  | 4 Pages

    A racemic mixture is a mix of equal numbers of enantiomeric molecules. Each enantiomer rotates plane-polarized light in an equal but opposite direction and is optically inactive because they are mirror images. when an optically active compound is synthesized, the product formed is found to be an optically inactive racemic mixture containing equal amounts of both l and d forms. The process where enantiomers are separated into l and d forms is referred to as “resolution”. the mixture is then said to

    have heard the term mixture in our Chemistry books or in the kitchen, But what the mixture exactly is? A mixture is an outcome of combining two or more substances without any fixed ratio and such approach that there is no chemical reaction occurs between them. The mixture is classified into two categories, one of them is the Homogeneous mixture, and another is the heterogeneous mixture. On mixing up the component substances retain their own identities and properties. Mixtures do not have a firm composition
