Title: Estimation of Ascorbic acid Aim: To determine the ascorbic acid content of canned apple and orange juice To determine the volume of canned juice necessary to provide 75mg of Vitamin C Introduction: For the estimation of ascorbic acid‚ the method used involved the titration of the ascorbic acid‚ in the presence of a redox indicator 2‚6-dichlorophenol-indophenol (DCPIP) which acts as both an oxidant so as to oxidise the ascorbic acid to dehydroascorbic acid‚ and it acts as an indicator

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

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

What is acetylsalicylic acid? Acetylsalicylic acid (ASA)‚ or more commonly known as aspirin‚ is a medication that can be used for pain‚ fevers‚ and inflammation. It can be used for long periods of time‚ in small amounts‚ to prevent heart attacks‚ strokes and the formation of blood clots. A heart attack victim can be given a low dose right after the ordeal to reduce the risk of another one. Side effects of this drug is ulcers‚ internal bleeding (stomach) and ringing in the ears. These mainly happen

For a base control‚ two non-colonized patients were randomly selected for every colonized patient. In the examination of future MRSA infections only lower respiratory tract (LRTIs) and bloodstream infections (BSIs) were considered‚ as they are the most common (Ghidey et al‚ 2014).

Everyone has a different point of view and after reading The Scarlet Letter by Hawthorne‚ The Letter from Birmingham Jail by Martin Luther King Jr.‚ Laws Scarlet Letter by Korobkin and Lyceum Address by Lincoln‚ it is important to follow ones conscience. This may seem unjust‚ but is it just to support an unjust law? This is where the controversy comes
