Acid-Base Titration and Volumetric Analysis The purpose of this experiment is to determine the [NaOH] of a solution by titrating it with standard HCl solution‚ to neutralize a known mass of an unknown acid using the NaOH solution as a standard‚ to determine the moles of NaOH required to neutralize the unknown acid‚ and to calculate the molecular mass of the unknown acid. Procedure: Part A: Standarized 0.10M HCl solution and unknown NaOH solution were poured into two beakers. The burets

Introduction Background Information To begin a discussion about acid-base titrations‚ we must first recall that there are several definitions of acids and bases. For the purpose of this exercise‚ we will consider the Arrhenius definition of acids and bases‚ in which an acid is a proton (H+) donor and a base produces hydroxide (OH-) in solution. When an acid reacts with a base‚ the products of this reaction are water and a salt. Note that salt here does not only mean table salt (NaCl)‚ but can refer

1. The film states that the Plea bargain is a "necessary evil" in order for our justice system to function. However‚ we also saw how it can be detrimental to the lives of those who plea. Do you believe the benefits to society outweigh the cost to the individual? Or does it really end up costing society in the end? Please discuss‚ make sure you mention some of the cost and benefits in your answer. -The benefits to plea-bargaining for society do not outweigh the cost to the individual because

What are the annual growth rates for the U.S. economy over the last 5 – 10 years? 2003/2.5%‚ 2004/3.5%‚ 2005/3.1%‚ 2006/2.7%‚ 2007/1.9%‚ 2008/-0.3%‚ 2009/-3.1%‚ 2010/2.4%‚ 2011/1.8%‚ 2012/2.2% Has GDP been growing or declining over this time-frame? You can see that over the years the growth rate can grow or decline. There was a decline from 2007 to 2009 compared to previous years but I came back up in 2010. In my opinion it looks that the growth rates pretty much stays between a certain percentages

to determine the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium permanganate‚ KMnO4‚ as the titrant in
