Prelab for Calibration of Volumetric Glassware

1). Weigh a 50 mL Erlenmeyer flask. Make sure the glassware is clean and free of any cracks or stars. Also, take note of the temperature of water, as volume varies with temperature 2). Transfer a portion of the water to flask with a pipette and record the mass of flask with the water. Use…

Impure Sodium Carbonate

Introduction: To determine the total amount of carbonate in unrefined sodium carbonate, soda ash, a titration is done using a standardized solution of HCl. Aqueous HCl is a strong acid and therefore almost completely disassociates into H+ and CL-. Therefore, when HCl is used in a titration, the H+ is the titrant. Carbonate in aqueous…

Analysis of Commercial Bleach

Introduction: Many commercial products are effective because they contain oxidizing agents. Some products that contain oxidizing agents are bleaches, hair coloring agents, scouring powders, and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite, NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution…

Lab Report on Acid-Base Titration

1. Aim: To determine the weight-to-volume percent of acetic acid present in commercial vinegar and the weight-to-volume percent of ammonia present in window cleaners. Acid-base titrations can be conducted using the above samples against standardized aqueous NaOH and standardized aqueous HCl solutions respectively. 2. Introduction: Acetic acid, commonly known as ethanoic acid CH3COOH, is found…

Neutralization Titrations: The Determination of Soda Ash

I.Purpose: The goal of this experiment is to determine the weight % of Na2CO3 through the preparation of NaOH and HCl standards. The molarity of the standards will be found through titration of KHP for NaOH, HCl vs the known NaOH, and the unknown Soda Ash sample vs the known HCl. II.Equations and Sample Calculations:…

Determination of nickel

INTRODUCTION EDTA (H₄Y) is widely used to determine metals in complexometric (a volumetric analysis where the formation of a coloured complex is used to indicate the end point of a titration) titrations as it forms stable complexes with most metal ions. EDTA is a tetracorboxylic acid and in alkaline conditions, it exists as Y⁴⁻ ions,…

Titration of Acids and Bases

Introduction According to Arrhenius definition, acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to…

Redox titration

To determine the x in the formula Fe (NH4)2(SO4)2i?? xH2O by titration against a standard solution of potassium manganate (VII) (permanganate). Theory: The experiment involves a redox reaction between potassium manganate (VII) and ammonium Potassium manganate (VII) is used in the experiment as it reacts completely and it is its own indicator. Potassium manganate (VII)…

To Determine the Content of Iron in Iron Tablets by Titration

PROCEDURES: Making a solution of the tablets 1. 5 iron tablets were weighed accurately, and then dissolved in about 100cm3 of 1.0 moldm-3 sulphuric acid in a conical flask. Some heating was required, but not more than the necessary needed to dissolve the tablets. 2. The mixture was filtered into a beaker, making sure that…

Finding our how much acid there is in a solution

The results and calculations clearly show what I believe to be an accurate concentration of sulphuric acid. I carried out the experiment as stated in my method 3 times after doing a rough test. This rough test was not included when I worked out my average titre. All my results were within 0. 2cm3 of…

Who’s cheating on the vinegar?

A chip shop owner buys his vinegar from 4 different suppliers A, B, C and Safe way. He suspects that at least one of them waters down the vinegar supplied to them by the manufacturer. You are the analytical chemist assigned to investigate this. You have already planned an experiment that will give you the…
