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

Another feminist aspect Ruth obtains is her protesting. A devoted traditionalist‚ Ruth defends the tribal ways of the A’tsika people and heavily protests Dwight and the corrupt councilmen when they accept a deal from the Japanese to kill a whale and try to cover it up by saying the whale killing will be returning them back to tradition‚ or as Dimitri said "will bring us back to ourselves" (Hogan 69). Even when the men invade and destroy her property‚ she persists in trying to get them to not go

Many people prefer freshly squeezed juice or juice bottled without added colouring‚ flavours and preservatives‚ over juices made of unhealthy and artificial ingredients. Because such products are not always readily available in supermarkets‚ some consumers make their own juice or patronize fresh juice businesses. There are many ways to run a fresh juice business‚ and it can be a very profitable and rewarding venture. To ensure your juice business is successful‚ you can do many things. Step 1

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

The purpose of this experiment is to separate a solution of an acidic and organic compound and purify its respective acidic product through the techniques of an acid base extraction‚ recrystallization‚ and use of Melt Temp (melting point range). The reaction of an unknown acid (3-chlorobenzoic acid) with diethyl and sodium hydroxide was observed‚ and the solution naturally separated into an aqueous and organic solution. The mixture of acid and organic solution was created and then separated through
