material in order to identify the type of metal. We used the water displacement method and the buoyancy method according to Archimedes Principle. Part II was to find the density of ethanol by mass. We used a 25.0mL graduated cylinder and a 25.00mL volumetric flask to measure the volume. We used two different pieces of glassware to determine the most accurate density of ethanol by mass since the measurement of volume is variable. Procedure: As stated in lab manual pages 23-24.

CHAPTER I AIR POLLUTANTS: SOURCES AND CONTROL OF GASES Introduction: 1. According to the World Bank‚ in 2007 air pollution cost about 3.8% of China’s 2. gross domestic product‚ mainly from diseases and loss of lives. 3. World Health Organization estimates that in India alone about 500‚000 premature deaths are caused each year by indoor air pollution. 4. Serious respiratory disease-related problems have been identified for both indoor and outdoor pollution in major cities of several countries. 5.

Analysis of Commercial Vitamin C Tablets Aim: To employ iodometric titration to determine the content of vitamin C in commercial tablets using volumetric analysis and compares it with the manufacturersÂ’ specifications. Introduction Vitamin C is an essential substance for maintaining good health and it is proved to be the agent which prevents scurvy. Most animals can synthesize their own vitamin C‚ but some‚ such as human cannot. Owing to the increasing concern for oneÂ’s health

Solubility and Stoichiometry I. Introduction The first purpose of this experiment is to apply solubility rules to choose two of eight given reactants to do a precipitation reaction. The second purpose is to use stoichiometry to calculate how much of a reactant will be used in a precipitation reaction‚ assuming that the amount of product is given‚ and to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. The other purpose of this experiment is to practice the
