Such fires should be extinguished with a wet chemical extinguisher. Really helpful material, saved me a great deal of time. The fatty acid source also affects the soap's melting point. Colorless less thick clear slight yellow like cook oil. The answer to this question isn't simple because we can't simply calculate a molecular weight for olive oil due to the fact that the chemical makeup of any container of olive oil may be different. Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions). Why is this portion water-soluble? Add 20 drops of canola oil to test tube #1. Buttercup Description, The experiment can be performed safely if proper precautions are observed.
