Titration

There are many instances in today’s society and on this planet, where it is crucial to figure out the unknown concentration of a known substance. The process that is used to figure out the unknown concentration of a substance 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 discovery of a concentration of…

For the following lab, the purpose is to utilize titration to determine the amount of ascorbic acid (vitamin C) present in a substance by reacting it with potassium bromate. An oxidation reaction takes place with ascorbic acid to produce dehydroascorbic acid, using an excess of bromine. The total amount of bromine utilized during the experiment is determined utilizing a back titration, in which the bromine is reacted with bromate. One mole of bromate produces three moles of bromine and the…

Lab 14/ Test 6: Determination of Acid Dissociation Constants through Titration Sabrina Tom I.Abstract The two unknown solutions A and E were titrated with NaOH solutions. For each solution, one fast and three slow titrations were done to see where the pH rose exponentially. The unknown solutions A and E were determined to be Pyridinium ion acid and oxalic acid, respectively. II.Theories One significant concept throughout this lab is titrations. A titration is a lab method analyzes a…

unknown base concentration of a sodium hydroxide solution can be determined by titration potassium hydrogen phthalate (KHP) with an unknown concentration of sodium hydroxide NaOH. The average molarity of NaOH determine by the moles and volume of the KHP and NaOH. (Eq 1). KHC8H4O4(aq) + NaOH(aq) = H2O(l) + NaKC8H4O4(aq) (Eq 1) The unknown concentration of white vinegar can be determined by the white vinegar with the known concentration of…

INTRODUCTION 1.1What is an acid-base titration? An acid –base titration is the determination of the concentration of an acid or base by neutralizing the acid or base with an acid or base of known concentration. An acid-base titration is the analysis of the concentration of acids and bases; through this process an acid or base of known concentration neutralizes an acid or base of unknown concentration. The neutralization of an acid or base in acid-base titration can be measured with either a…

characteristics of acids and bases by investigating the characteristics of strong versus weak 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.…

2015 Lab Report Concerning Acid-Base Titrations The purpose of this experiment was to recognize the procedures for conducting acid-base titrations. Each acid-base titration used one solution to analyze another; it also involved the use of an indicator, which denoted the endpoint of the titration. The indicator used was phenolphthalein; it produced a pink hue when the titrations reached their endpoints – between pH 8 and pH 10. The endpoint was reached when the moles of the base being used…

This study involves the use of redox titration to determine the amount of oxalic acid in the sample solution. The analyte solution containing oxalic acid was added with sulfuric acid and heated prior to the titration with permanganate. The persistent pink color signaled the end of the titration. The amount of the oxalic acid in the solution was found to be 8.941%. The redox titration was precise in the quantification of oxalic acid with a standard deviation of 1.327%. Introduction One of the…

in Carbonated Beverages Abstract: The basis of this lab was to juxtapose two different titration methods in their ability to identify the end point, calculate the molarity of citric acid in the two sodas, and apprehend the differences between polyprotic and monoprotic acids. In order to accomplish this, a traditional titration, with phenolphthalein, and a modern titration, with a pH probe, were executed. Through the use of the equation for molarity and stoichiometry, the molarity of…

of the Concentration of Acid in Gastric Juice Introduction Titration is a method where a solution of known concentration is used to find the concentration of an unknown solution. A standard solution is a solution of precisely known concentration. The aim of this experiment was to go over the use of pipettes, burettes, titrations and also to reinforce the concept of molarity. In this experiment, a titration was carried out using a standard solution of hydrochloric acid to establish the…
