Lab 12: Saponification – Making Soap Objective: To make soap using the process call saponification, an organic form of the neutralization reaction that an acid reacts with a base to form a salt. Introduction: A soap is the sodium or potassium salt of a long chained carbohydrate called a fatty acid. A fatty acid usually contains between 12 – 18 carbon atoms. Fatty acids are esters of either animal or vegetable fats. They are called triglycerides if they are solids at room...

Writing polyprotic acid and base reactions: 1. Write all the dissociations for the three polyprotic acids: H_2CO_3, H_3AsO_4, H_3PO_4. Match the appropriate Ka1, Ka2, Ka3 values to the dissociation reaction. 2. Identify all the species in each of the reactions as either an acid, a base, or amphoteric. Imagine putting NaH_2AsO_4 in solution. This is a salt. Describe, using chemical equation, exactly what happens? First write the dissociation reaction of the salt. Then identify the pH active species, and then...

For the following questions answer with as much detail as possible. If a metabolic pathway is involved draw a name all molecular structures and name all enzymes. Indicate cell type and location within the cell as well as any transport mechanisms. Since the fatty acid pathways are serpentine, show one pass through the sequence and then you may simply state how many times a sequence is repeated until a new reaction is needed. If asked to synthesize a fatty acid,...
