AbstractWe prepared soap with a mixture of sodium(Na+) salts and long-chain carboxylic acids obtained from the chemical process of hydrolysis(breakdown of a compound due to a reaction with water). For this we weighted, on a scale, 8 grams of sodium hydroxide(NaOH). As this was happening, a hot plate was heating up 25 ml of water. We then added the sodium hydroxide pellets to the water and stirred continuously with a glass rod until a clear solution formed. When this happened, we took this solution off the hot plate and placed it on the side as we needed the hot plate for our next step. The hot plate temperature was put on “low” as we placed 58 grams of Crisco vegetable fat on a 250 ml beaker. The vegetable fat was put on top of the hot plate for several minutes until the fat completely melted. The fat was put to cool down, then the lye(alternative name for NaOH) solution was added. This created a light yellow mixture and was placed in a plastic cup to age for two weeks. When making calculations about how much should
