Ever since I was a little girl I dreamed about traveling overseas. Strange lands‚ exciting places‚ and new cultures have always fascinated me. I’ve always wondered what it would be like to speak another language‚ to grow up learning different customs‚ or to live in a completely different way than I do now. This past summer my dream finally came true. I got to travel to England‚ France‚ Switzerland‚ and Germany with Mme. Kelly and five other girls‚ and suddenly the world was at my fingertips. <br> <br>England’s

6. FIRST DERIVATIVE ZERO CROSSING METHOD 6.1. ABSTRACT: Simple‚ specific‚ accurate and precise 1st order derivative zero-crossing spectroscopic method was developed for simultaneous determination of PHENYLEPHRINE and EBASTINE from their binary mixture. In this 1st derivative zero-crossing spectroscopic method the amplitudes of the 1st order derivative of the spectra of the binary mixture containing PHE and EBS were measured at 252.2 nm (zero crossing of EBS) for determination of PHE and at 274.8

Experiment 5- Standardization of NaOH and determination of Molarity of an unknown Acid Objectives 1. Preparation and standardization of a 0.1M NaOH solution 2. To learn the technique of titration 3. Determination of the concentration of an unknown diprotic acid. Introduction Titration can be traced to the origins of volumetric analysis‚ which began in the late eighteenth century. Study of analytical chemistry began in France and the first burette was made by Francois Antoine Henri

Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding

The 13C NMR spectrum was useful to help finding the structure of the unknown. It showed six different signals in the spectrum. Signal 1 had an observed peak value of 19.242 ppm‚ and its peak calculated value was 19.1 ppm. This signal was first to most upfield and shielded in the spectrum because of the high electron density of carbon. This signal was agreed to a literature value for a CH3 group between 5-30 ppm. Signal 2 was branched to signal 1‚ and had the same value‚ but it was agreed for the

Case Study Report for Unknown #49 A new school for girls was opened in a larger village in Northern Pakistan‚ and the teachers were proud to have convinced many families in the surrounding villages to allow their daughters a basic education. The school was a success‚ and the 6-10 year olds girls quickly learned how to read and write and were even instructed in the sciences. However‚ 2 weeks before summer break‚ many of the girls and the teacher developed breathing problems that included severe coughing

Sally Jessica Smithers: The Case Of The Unknown Assassin Sally Jessica Smithers was a slender‚ beautiful‚ smart‚ and talented cop. She was investigating eleven serial killings of important men when she got a call‚ there was another murder. When she went‚ she took no time at all at the scene. As Sally left the crime scene in the park‚ with one hand in her long dark brown hair‚ she called out to a few units to make three immediate traffic stops and went to the last one to read off people’s IDs.
