Fat and Oil Saponification value of Fat and Oil Acid⋅base titration (non aqueous) by Automatic Potentiometric Titrator Standard JIS ASTM ISO K 0070 D 5558 3657 Standard Test Method for Fat and Oil 1.Abstract Saponification value is expressed by potassium hydroxide in mg required to saponify one (1) gram of fat. It depends on the kind of fatty acid contained in the fat. Measurement of saponification value is performed according to the below listed official test methods. Here we test a sample of

Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to

AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with

Acid Rain Definition: The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852‚ when the English chemist Robert Agnus invented the term. From then until now‚ acid rain has been an issue of intense debate among scientists and policy makers. Acid rain‚ one of the most important environmental problems of all‚ cannot be seen. The invisible gases that cause acid

replace bad fats with good ones that promote health and well-being. Polyunsaturated fats is one of two main fats. When you pour liquid cooking oil in a pan‚ there’s a good chance you’re using polyunsaturated fat. Corn oil is a common example. Polyunsaturated fats are required for normal body functions‚ but your body can’t manufacture them and so must get them from food. Polyunsaturated fats help build cell membranes‚ the exterior casing of each cell‚ and the sheaths surrounding nerves. They’re vital to

Ethanoic Acid Advantages: Ethanoic acid is non-toxic and is a weak acid‚ meaning it will not do any damage to most surfaces as it does not corrode or bind to other metals‚ therefore can be easily removed through washing or rinsing it. Disadvantages: Ethanoic Acid is the slowest de-scaler of the three acids‚ and is therefore the least effective. It also may cause an unpleasant smell‚ and can have a negative effect on the taste of coffee meaning one would need to spend longer time rinsing and cleaning

Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.
