Determination of acetic acid in vinegar using acid-base titration 1. Scope The goal of this analytical procedure is to determine the acetic acid content of two samples of vinegar produced by Kolinska‚ Ljubljana‚ Slovenia. These samples are: Sample No. 1: vinegar made from wine‚ 4% Sample No. 2: vinegar made from alcohol‚ 9% The smallest quantity of the sample is 100 mL. Interesting results may be obtained by comparing the acidity of both samples of vinegar with factory analysis data. 2. Principle

of several structural units bound together by covalent bonds [1‚2]. For example‚ polyethylene is a long-chain polymer and is represented by ÀCH2 CH2 CH2 À or ½ÀCH2 CH2 Àn ð1:1:1Þ where the structural (or repeat) unit is ÀCH2ÀCH2À and n represents the chain length of the polymer. Polymers are obtained through the chemical reaction of small molecular compounds called monomers. For example‚ polyethylene in Eq. (1.1.1) is formed from the monomer ethylene. In order to form polymers‚ monomers

INTERNET FOR ALL – PROJECT LOON Akash James Engineering Student‚ Reva Institute of Technology and Management. ABSTRACT: Connectivity to the Internet is a vital technological requirement. It’s arguably one of the best and most transformative technological advancements of our species. However‚ approximately 4.3 billion people who still live in rural and remote regions where telecommunication is scarce or absent are not gifted with a connection to the World Wide Web. These are mainly due to terrestrial

Waste management is the collection‚ transport‚ processing‚ recycling or disposal‚ and monitoring of waste materials. The term usually relates to materials produced by human activity‚ and is generally undertaken to reduce their effect on health‚ the environment or aesthetics. Waste management is also carried out to recover resources from it. Waste management can involve solid‚liquid‚ gaseous or radioactive substances‚ with different methods and fields of expertise for each. Waste management practices

plastic alternative. Properties of PHB... The biodegradability of PHB gives it extraordinary appeal as a potential replacement for the widely used polymers derived from petrochemicals. These petrochemical products‚ such as polypropylene and polyethylene‚ are often used for packaging‚ but are a hazard to the environment because of the fact that when discarded they do not decompose and can cause injury to plants and animals. PHB however can be completely broken into carbon dioxide and water by bacteria

------------------------------------------------- Definition Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group‚ and most commonly from carboxylic acids and alcohols. That is‚ esters are formed by condensing an acid with

The first man made plastic wasn’t introduced until 1862 by Alexander Parkes who discovered Parkesine. This plastic had the ability to mold when cooled. It wasn’t until a cheap alternative way to bottle water was discovered with a new plastic‚ polyethylene. In the late 1960’s water began being produced and sold commercially in water bottles. Since then huge companies like Aquafina and Dasani have taken over the water bottle industry alongside many other brands that mass produce water in new types
