Amperometric titration

acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base titration, weak acid and strong base titration, and the pH measure of a salt solution. In performing a titration, a stir-bar, stir-plate, burette and pH meter. In the process of titration, it is required that the amounts of base added from the burette is…

Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved…

is the process known as titration. Titrations are used in a wide range of work environments including forensic labs, and pharmaceuticals. A way in which titrations could aide society could start in a forensic lab. It could be used when trying to figure out the concentration of a drug or poison that may have been used in a crime. In a pharmaceutical environment it could be used to properly give out the dosages to patients that require medicine. The method of titration can be defined as the…

CH 204- Introduction to Chemical Practices Experiment 1- Qualitative Analysis of Cations Sharon Alexander Kathrynn Labat TA: Yu-Chun Lin September 25, 2017 Results & Discussion This experiment was composed of three parts. In the first part, qualitative methods were used to identify the unknown cation in an aqueous solution. The cation was to be either lead or silver. If silver was present, extra steps were needed to be taken in order to confirm its presence in the…

In part A , we will start with our given solution of and synthesize a number of copper compounds by chemical reactions and observing every colour change and…

Purpose: The purpose of this lab is to prove and discern the empirical formula of copper oxide using the Law of Conservation of Mass. This states that in measuring the mass of each component of copper oxide and determining the percent composition of each the copper and the oxygen within copper oxide it is possible to find the ratio of the elements within the compound. Procedure: In order to conduct this lab, 25.1mL of distilled water then 25.5mL of 3M HCl must be added 2.11g of copper oxide.…

Conclusion: I predicted that liquid A was glycerine due to a calculated density of 1.38 g/mL. However I was wrong the actual density of liquid A was 1.38 g/mL and the substance was actually corn syrup. Therefore the percent of error for the density of liquid is 1%. For liquid B I had predicted that its substance would be Glycerine due to the calculated density of 1.19 g/mL. I was incorrect for the density of liquid B which was actually 1.26 g/mL, but because the calculated and actual densities…

The two main purposes of the lab were to determine the percent by mass of acetic acid in vinegar and to determine the molar concentration of a strong acid. In both parts of the experiment a volumetric analysis was used. This is primarily the aid of volumetric glassware in order to determine specific measurements and calculations. Potassium hydrogen phthalate was used as the primary acid standard to determine the molar concentration of the sodium hydroxide solution in part one of the experiment.…

Conclusion The empirical formula of the copper chloride hydrate compound is CuCl2 · 2H2O. Discussion of Theory The technique of gravimetric analysis can be used to find the empirical formula of a compound when the amount of it is known. By dehydrating the copper chloride hydrate sample and using it for an elemental copper-producing chemical reaction, one can isolate the masses of the water, copper, and chloride and determine their mole ratios. Since the Law of Definite Proportions states that a…

Ethyl vinyl ether was used to protect –OH on glycidol based on a literature reported protocal.59 In a typical procedure, 0.675 mol glycidol and 200 mL ethyl vinyl ether were loaded in a round-bottom flask, to which 1.25 g TsOH was then added. The reaction was allowed to proceed at room temperature (RT) for 3h. The resulting mixture was then purified by washing with 100 ml saturated aqueous solution of NaHCO3 for 3 times. The organic layer obtained was dried by MgSO4. After filtration of MgSO4,…
