Titration

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.

Titration was performed over two weeks to determine the amount of acetic acid in vinegar. On the first week, the purpose of the experiment is to standardize a 0.500 M of NaOH solution to be used in week two. Since the stock solution was in 5.0 M NaOH, dilution of the solution was performed to make 0.500 M NaOH solution. On the first week, 40 mL stock solution was diluted with 360 mL of water to attain a 400 mL .500M NaOH. This method is considered imprecise because the concentration of stock solution

A titration is a method to determine the concentration of an unknown solution by using the known concentration of another solution. An analyte is the concentration of an unknown solution . A titrant is the concentration of a known solution. The glassware needed to perform a titration are a buret, a flask, and an indicator of pH meter. The buret sends the second reactant to the flask. An indicator detects the endpoint of this reaction. Standardization is the process in which you determine the concentration

Titration is a method used to determine an unknown concentration of a known solution. Through this, we may know the chemical that can be dissolved, but not how much of the chemical could be in a specific solution. The purpose of this lab is to be able to determine the concentration of a hydrochloric acid solution using acid base titration in where hydrochloric acid solution is a strong acid and sodium hydroxide is a strong base. In experiment 1, I perform a coarse titration. A coarse titration is

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

Iron Titration Practical Introduction into Treating Anaemia with Iron Tablets Anemia, which is a condition that develops when there is a lack of red blood cells or isn’t enough healthy cells to support the body. The symptoms are:  Extreme fatigue  Pale skin.  Weakness.  Shortness of breath.  Chest pain.  Headache.  Dizziness or light-headedness. Causes of Anaemia can vary depending on the person. Iron Deficiency Anaemia can be caused by bleeding, for example if a person has lost blood

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

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

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
