    would changed colours from colourless to pink indication when enough KOH(aq) was added. The purpose of numerous trials was to use the average volume of the 3 trials with similar measurements. Purpose The purpose of this lab was to use process titration to find concentration of an aqueous solution of Hcl(aq) , using KOH(aq) as the titrant. Results Table 1.0: Information gathered during the trial: The volume of KOH(aq),titrant, used in different trial. Trial 1 2

    Laboratory: Titration of an Acid with a Base Tristian Pérez Rivera 12-136 AP Chemistry Professor Judith Martínez PhD Objective * The purpose of this laboratory is to recreate and understand what titration is. Hypothesis * If the experiment works correctly, we should determine the amount of a substance by adding a carefully measured volume of a solution with known concentration until the reaction of both is complete. Materials * Computer Pre-lab 1. How will you know when your titration is finished

    oxidizing agent. In this lab, a solution of KMnO4, an oxidizing agent, will be standardized by titration with a solution containing a known concentration of iron (II) ions, (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution of

    acid-base titration. In part A of this experiment, the molarity of an assigned concentration which was 0.040, was found using formulas that represent molarity. Part B of this experiment, which was titration of an acid and base, was found by a series of steps that involved dropping Sodium Hydroxide from a buret into vinegar, until the perfect shade of pale pink occurred. With the Phenolphthalein, too much acid causes the base to turn a dark pink. The molarity was then found of the titration. So the

    For this experiment, a titration was performed to determine the unknown concentration of a given HCl sample by reacting it with a solution of sodium hydroxide. NaOH first had to be standardized due to it being hygroscopic. A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.1 The titration of KHP with NaOH was the standardization process which determined the actual concentration of NaOH. This value helped determine the volume of

    The purpose of the iodimetric back titration, a form of redox titration, experiment is to determine the weigh percentage of ascorbic acid in Vitamin C tablets. The experiment is performed by titrating iodine solution that contains the dissolved ascorbic acid with sodium thiosulfate. The results of the titration was inconclusive, and the weight percentage of the ascorbic acid could not be determined. Several sources of error could explain the variation of titrated volume of sodium thiosulfate.

    In this lab, a titration was performed in order to calculate find the concentration of hydrochloric acid. In the first part of the lab, the hydrochloric acid was then titrated with sodium hydroxide to obtain the concentration of the hydrochloric acid. In the second part of the lab, a base and/or antacid was over titrated with hydrochloric acid. It was then back-titrated using sodium hydroxide solution to determine how much hydrochloric acid was needed to neutralize the titration. Throughout the first

    The Objective of the lab is to determine the mass percent of ascorbic acid in a vitamin C tablet by titration with a sodium hydroxide solution of known concentration. A titration is a procedure in which we measure the volume of a solution of a solution of known concentration that is needed to completely react with volume of NaOH analyzing. A buret is used to measure the amount of NaOH in titration and it is a piece of calibrated glassware used to accurately deliver volumes of a liquid or a solution

    Quantitative Chemistry –Titration Determination of the Molarity of an Unknown Solution through Acid-Base Titration Technique 1. Introduction 1.1 Aim The aim of this investigation was to determine the precise molarity of two (NaOH(aq)) sodium hydroxide solutions produced at the beginning of the experiment through the acid-base titration technique. 1.2 Theoretical Background Titration is a method commonly used in laboratory investigations to carry out chemical analysis
