Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

Acid Rain: The Southern Company (A) Problem Statement In 1992‚ executives at the Southern Company have three years to formulate a robust and complex strategy that will involve massive capital outlay and substantial modifications to processes and procedures as it works to comply with provisions enacted in 1990 to the amendments of the Clean Air Act‚ while simultaneously ensuring they remain sustainable and profitable. Analysis The Southern Company is an American based electric utilities

BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo‚ and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of amino acids. A series of

Acetic acid‚ a pungent smelling colourless liquid having sour taste‚ used very commonly in the chemistry laboratories. It got its name from Latin word Acetum‚ which means vinegar. Pure acetic acid is also called glacial acetic acid‚ because in winters it freezes easily as temperature goes below 16-17°C. Therefore it looks like as if a small glacier is there in the bottle‚ hence called glacial acetic acid. Laboratory and daily life uses of acetic acid are: (i) Acetic acid is used in household kitchens

Sulfuric Acid is one of the the important chemical compounds. A Great amount of sulfur is mined all around the world and is used to produce sulfuric acid. Sulfuric acids being produced Sulfuric acid may seem like something to find in a lab‚ perhaps under the label “corrosive‚” and in some kind of tube that isn’t affected by it. But‚ in reality‚ it’s quite common‚ and is used often in the industrial business‚ for many different objects. Because of this‚ many places can often be judged upon their

of Acetylsalicylic Acid Abstract Acetylsalicylic acid was prepared using salicylic acid and acetic anhydride. As a result‚ a white‚ powdery substance was formed (0.1931g‚ percent yield 91.30%) and was defined by melting point (124.5 – 134.5°C) and observation of color change with ferric chloride. Introduction Acetylsalicylic acid (aspirin) is one of the most popular analgesic drugs on the market today. It also acts as an antipyretic and anti-inflammatory drug. Salicylic acid itself was too acidic

We will also be practicing how to prepare the solution. Using the titration data‚ we can practice our stoichiometric skills and also become more familiar with using lab equipment. Titration is the process of measuring the exact volume of a solution of known concentration that is

Introduction: In this lab‚ we measured the acid-base strengths of seven separate organic compounds. The lab was painless to perform‚ it consisted of adding a small amount of one of the organic compounds to a well‚ and testing the pH via testing paper. The color of the paper was then analyzed to determine what the pH of the compound was. The structures were benzenesulfonic acid‚ benzoic acid‚ benzyl alcohol‚ benzylamine‚ p-cresol‚ and p-toluidine. My initial hypothesis about the acidity/basicity
