experiment is to determine the concentration of acetic acid in vinegar by using 0.1 M HCl and NaOH solution. By performing three titrations to determine the concentration of the base‚ the concentration of the acid was determined to be 0.600 M. It was possible to determine its concentration by standardizing the sodium hydroxide solution used for the first three titrations and by using phenolphthalein to indicate its equivalence point. In conclusion‚ although there were sources of error‚ the hypothesis

Titration is a method used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately

Discussion In the model systems (solutions and paper)‚ which samples browned the fastest and why? Which samples did not go brown and why? Why did the paper brown so rapidly compared to the solutions. What caused any significant differences between the model and real systems? In particular are there other ingredients in the cookie that could take part in the reactions or is the heating different in some way? Sample A and sample B are overlap after fry the paper. Sample B is more browning

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be detected

DKFLSDFKLFKJ | Acid-Base Titration. | kfjhdkjhvdkfj | | April Jowers | 12/19/2012 | DKFJSDKJFHDSKJHF | Introduction In this lab we will use basic titrating skills and techniques in order to titrate HCl. We will also be practicing how to prepare the solution. Using the titration data‚ we can practice our stoichiometric skills and also become more familiar with using lab equipment. Titration is the process of measuring the exact volume of a solution of known concentration that is

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
