Silver Nitrate Titration Introduction This experiment was conducted to work out the concentration of the chloride ions in the school swimming pool water and to see if it fits in the required range of concentration of chloride ions in the swimming pool water. This was done by titrating a small sample of the school swimming pool water with silver nitrate‚ which would form a white precipitate of silver chloride. The equation of this process is: The end point of the titration (when all of

From the trading account‚ profit and loss account and the balance sheet‚ the solvency or liquidity‚ profitability and performance can be worked out for 2008 for C & V Fashions. These types of ratios can be analysed once worked out to assess the performance of the business. The current ratio and acid test ratio both show that C & V Fashions were solvent this year and that they are able to pay of their debts. As well as being able to pay off their debts‚ the business has some capital left over

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

CHAPTER 1 INTRODUCTION 1.1 Background of the Research Vitamin supplements bring added nutritional values to people’s health. With their contents of the certain recommended amount of minerals and vitamins needed for staying healthy‚ vitamin supplements have become more and more popular especially for those with hectic and busy lifestyles. These people believe that daily or regular consumption of vitamin supplements helps to ensure the proper intake of nutrition needed—a compensation for what

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 in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell‚

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

Experiment 2 Acid/Base Titration John J. Purdue CHM 321 – Fall 2012 TA: Scott Cole Section 1 September 4‚ 2012 Unknown Concentration: X.XX ± X.XX M (@95% confidence interval) (adapted from a report prepared by N. Skrynnikov‚ 2009) Abstract The concentration of an unknown acid (HA) solution was determined by titration with a standardized solution of sodium hydroxide. The standardization of NaOH was done by titration with a solid acid sample‚ potassium hydrogen phthalate (KHP)‚ and phenolphthalein

Determination of An Unknown Amino Acid From Titration Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96‚ and the pKa’s found experimentally were 2.0‚ 4.0‚ and 9.85. The accepted pKa values were found to be 2.10‚ 4.07‚ and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid‚

Hepatitis C 12/02009 By: Shuntrice Hannah Abstract Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). It is difficult for the human immune system to eliminate the virus from the body‚ and infection with HCV usually becomes chronic. Over decades‚ chronic infection with HCV damages the liver and can cause liver failure in some people. The hepatitis C virus is transmitted mainly by contact with blood or blood products.
