samples of vinegar if any had been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt containing

Banana (Saba) vinegar Conner is known as the fruit basket. One of the fruits that are abundant here is banana. The word “banana” is a general term embracing a number of species or hybrid in the genus Musa of the family Musaceae. there are many different kinds of banana found in Conner those are the “Lakatan”‚ “Sinlowa”‚ “Tanda”‚ “Dippig tagalong” and “Dippig”. Bananas are good for dessert or for cooking description. Banana fruit or dessert is made of soft‚ easily digestible flesh with

on the pH of the Vinegar Introduction: For this experiment‚ the town council wanted to test which building material would be the best to build statues in a zoo. The building material with the lowest pH would be the best building material because while 7 is neutral anything below 7 is considered acidic and anything higher than 7 results in a base. Precipitation of 5.5 or lower is considered acid rain. Connecticut and most of the United States have to deal with acid rain. Acid rain occurs when

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example

How effective is Apple Cider Vinegar Pills on Weight Loss? Apple Cider Vinegar pill is considered a cure-all‚ boosting immunity‚ digestion improving and promoting weight loss medication. It helps in controlling of appetite‚ and shouldn’t be mistaken as a cure for obesity. How effective is it in weight loss? Acetic acid on Fat Loss Apples are a good source of pectin‚ which makes one feel fuller and more satisfied. Apple Cider Vinegar contains the same amount of pectin as apples thus it easily suppresses

EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U.S. is

Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of
