water. The fatty acid used in this experiment was Crisco vegetable fat, and the alkaline solution was NaOH mixed with water. This experiment is significant because it demonstrates how an everyday item like soap is made, and how it really works at a molecular level. Data: Type of fat used _________Crisco Vegetable Fat_______________Weight of fat taken __________57.84___________gWeight of NaOH used _________7.99__________gWeight of soap formed ________83.456___________gUse the weight of fat taken and the reaction to find the theoretical yield (weight) of soap bar?Theoretical yield______62.175_____g% yield = (actual yield (weight of soap formed)/theoretical yield) X 100= _____134.23_____%Discussion: A few anomalies in this experiment are the percentage yield at the end and the exact temperature at which the vegetable fat and the NaOH needed to be mixed. The concluding percentage yield was 134.23%, which indicates an error occurred during the procedure for this experiment. The temperature, at which the melted fat was supposed to be mixed with the alkalinesolution NaOH, was between 40-50OC. A mixture at a different temperature would have caused this anomaly. The theoretical yield of soap was calculated a moles to grams ratio and a moles to
