Titration test Alfredo Verzo III We have been provided with two samples of vinegar‚ one removed from a restaurant and one removed from a take-away. Trading Standards suspect these two establishments of watering down the vinegar. They need evidence that the samples contain less acid than the standard vinegar sample provided. What is the purpose of this? I’m a worker in the Trading Standards which carries out tests to see if restaurants and takeaways are watering down the vinegar. We will

English 1A: Discussion Topics John Berger’s “Ways of Seeing” Topic 1: Berger argues that there are barriers to vision‚ problems in the ways we see or don’t see original works of art‚ problems that can be located in and overcome by strategies of approach. For this topic‚ discuss what‚ as you read Berger‚ gets in the way when we look at paintings‚ and what it is that we might do to overcome the barriers to vision (and to history). Imagine that you are speaking to someone interested in art‚ but someone

Aim: To calculate the concentration of acid in a sulphuric acid solution. Introduction: A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and the precise quantity of reactant in the titration flask. A burette is used to deliver the second reactant to the flask and an indicator is used to detect the endpoint of the reaction. So a chemical reaction is set up between a known volume of a solution of unknown concentration and a known volume of

Lab 12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator

Observation Zinc Shot: Silver color‚ some pieces are shiny while the majority is dull. Tear shaped pieces (round at base with pointed top). No odor. Zinc Granular: Silver in color‚ semi shiny‚ flaky appearance. No odor. Zinc Sheet: Sheet of metal‚ flat pieces that are about 3 inches wide & 2 inches in length & 0.02 inches in height. Each piece has a dull side and a shiny side. Silver in color‚ the dull side has a darker shade of gray. No odor. Zinc Powder: Gray very fine powder. No odor

Condition your buret and filled with titrant solution. You should check for air bubbles and leaks‚ before proceding with the titration. 29. Take an initial volume reading and record it in your notebook. Before beginning a titration‚ you should always calculate the expected endpoint volume. 30. Put paper on the top loading balance
