So for every NaOH molecule that we add to the solution,we can expect to produce a hydroxyl ion. Sodium hydroxide is a strong base, which means that it dissociates almost completely in water. For the titrating solution, we'll use a dilute solution of sodium hydroxide (NaOH). a means of indicating when the endpoint has been reached. a method for delivering a precisely measured volume of the titrating solution, and 3. a titration solution (contains hydroxyl ions with a precisely known concentration), 2. In order for a titration to work, we need three things: 1. The hydroxyl ions will react with the hydrogen ions to Titration theory: To measure the acidity of a vinegar solution, we can add enough hydroxyl ions to balance out the added hydrogen ions from the acid. The concentration of the titrant can now be calculated from the amount of titrating solution added, and the ratio of the two chemicals in the chemical equation for the reaction. The titrating solution reacts with the titrant, and the endpoint of the reaction is monitored in some way. Titration is a way to measure the unknown amount of a chemical in a solution (the titrant) by adding a measured amount of a chemical with a known concentration (the titrating solution). Titration introduction: In this project, I have determined the amount of acid in different vinegars using titration, a common technique in chemistry. The amount of acetic acid in vinegar can vary, typically between 4 to 6% for table vinegar, but up to three times higher ( 18%) for pickling vinegar. There are many different types of vinegar, each starting from a different original sugar source ( e.g., rice, wine, malt, etc.). The fermentation of ethanol results in the production of acetic acid (CH3COOH). :: INTRODUCTION :: About Vinegar: Vinegar is a solution made from the fermentation of ethanol (CH3CH2O H ), which in turn was previously fermented from sugar. :: OBJECTIVE :: The goal of this project is to determine the amount of Acetic Acid in different types of vinegar using titration with a coloured pH indicator to determine the endpoint. 14.Ĭertificate Aim Acknowledgement Objective Introduction Apparatus Theory Experimental Procedure Experiment 1 Experiment 2 Experiment 3 Result Precautions Bibliography I would also like to extend ma gratitude to the entire Chemistry department of New Horizon Public School for their constant support. Without her motivation and help the successful completion of this project would not have been possible. ::ACKNOWLEDGEMENT:: I sincerely thank our Chemistry teacher Ms Pranalli for her guidance, encouragement and support throughout the duration of the project. Measuring the Amount of Acetic Acid In Vinegar by Titration with an Indicator solution. The progress of the project has been continuously reported and has been in my knowledge consistently. :: CERTIFICATE :: This is to certify that Miss Suparna Ghanvatkar of class XII has completed the chemistry project entitled ‘DETERMINATION OF AMOUNT OF ACETIC ACI D IN VINEGAR’ herself and under my guidance during the academic year 2011-12.
