Lacy Taylor iLab‚ Week #5 UNKNOWN ACID AND BASE TITRATION Introduction The pH‚ or the concentration of the hydrogen plus ion [H+]‚ is one of the most critical parameters in predicting if a system will corrode‚ or determining why a system is corroding. PH is defined as the negative log base 10 of the hydrogen plus ion concentration in the units of moles per litre. Procedure pH MEASUREMENT OF UNKNOWN SOLUTIONS Obtain the following apparatus from the equipment menu: 100 mL beaker

titrate the NaOH into the solution. Start the data collection to calculate the volume of NaOH is added when the solution reaches its equivalence point. Then right down the calculations and disassemble the apparatus. Discussion My lab group and I completed this experiment doing two trials. We found that both trials were concluded with similar results. In trial 1 we found that the volume of

Title: Candy Chromatography Background Information and Research: Paper Chromatogrpahy is a analytical method that is used for seperating and identifying mixtures of color. There are two stages‚ the stationary phase and the mobile phase. The first is for a solid and the second for a liquid or gas. -Reference http://www.chemguide.co.uk/analysis/chromatography/paper.html Purpose: To see how paper chromatography works. Materials: · Candy with a colored coating‚ like Skittles® or M&Ms® (4 different

Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf

esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006).

The injected sample becomes vaporized and was carried through the mobile column. It is usually carried by an inert gas. The gases were moved through the stationary column. The polarity of the components to the column would cause the separation of the components

MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total
