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...
