Saponification-The process of Making Soap ... - Online Lab- fats and oils soaps and detergents lab report ,Fats/oils from animal source are high in saturated and low in unsaturated fatty acids. SOAP. Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters.Oil and Grease Analysis | EPA 1664 Analysis | Caltest ...Sep 12, 2013·The mineral oils coat surfaces to a greater extent than fats, oils, and soaps, and the particles interfere with biological action and cause maintenance problems. EPA method 1664 uses n-hexane as the extraction solvent for Oil and Grease and other extractable material that is not adsorbed by silica gel in surface and saline waters, and ...
Unsaturated fat is found in fish like salmon and tuna, nuts, seeds etc. Some Important Tests for the Detection of Oils and Fats Solubility test. Oils and fats are soluble in organic solvents like, chloroform, alcohol etc. but are insoluble in water. Translucent Spot test. Fats and oils have higher boiling points so at room temperature they ...
Instructors Notes: Soap Estimated Time: 4 weeks The laboratory could be shortened by up to two weeks by missing out the detergent synthesis and the analysis of the waste water. Check in week After Check-in go over the lab with the students and explain the purpose: i.e. to synthesize and investigate the action of soaps and detergents.

\[Fat/Oil + Sodium\, Hydroxide \rightarrow Soap + Glycerol\] Fats and oils are esters made from glycerol and long chain fatty acids. Consider the hydrolysis of this triglyceride found in animal fat.
triacylglycerols (fats and oils), phospholipids and steroids. The fatty acids are usually not free in nature, but are components of triacylglycerols, waxes and phospholipids. Animal fats or vegetable oils (especially palm oil) are used to make soap. You prepared soap in an earlier experiment.
Today soap is manufactured much like it was over a hundred years ago: fats or oils are heated in the presence of a strong base (NaOH or KOH) to produce fatty acid salts and glycerol in what is called the saponification reaction. The salt of a fatty acid is the soap, a soft and waxy material that improves the cleaning ability of water.

Oct 20, 2019·Vegetable oils produce soap that is generally softer and gentler to the skin. There are exemptions of course. Coconut and Palm Kernel Oils produce soap that is hard and can be drying to the skin. These oils are made of short chain saturated fats that make excellent sudsy cleansing soap. So much so as they strip the skins natural oils. Therefore ...
May 21, 2013·The value is simply a measurement of the mg of KOH required to complete the hydrolysis of one gram of fat oil. For making the soap, sunflower oil had been used. The oil had been boil with 6.0M of NaOH. In the process of making soap, vegetable fat, which is triglyceride, is hydrolyzed by the action of strong base, such as sodium hydroxide, and heat.
May 22, 2013·The fats and oils that are most common in soap preparations are lard and tallow from coconut, palm, and corn oil from vegetable sources. The length of hydrocarbon chain and the number of double bonds in the carboxylic acid portion of the fat or oil determine the properties of the resulting soap.

The soap came to the top, was skimmed off, and placed in wooden molds to cure. It was aged many months to allow the reaction to run to completion. All soap is made from fats and oils, mixed with alkaline (basic) solutions. There are many kinds of fats and oils, both animal and vegetable.

Jun 15, 2018·Vegetable oils, with unsaturated carbon chains, produce soft soaps. Animal fats yield hard soaps. Coconut oils with shorter carbon chains, yield soaps that are more soluble in water. In modern commercial soap making, the fats and oils are often hydrolysed with super heated steam. The fatty acids then are neutralized to make soap.
Treatment of fats or oils with strong bases such as lye (NaOH) or potash (KOH) causes them to undergo hydrolysis (saponification) to form glycerol and the salt of a long-chain fatty acid (soap). Because soaps are the salts of strong bases and weak acids they should be slightly basic.
