Rey Vincent P. Antonio Experiment 8: Quantitative Determination of Copper Concentration in Aqueous Solution by Iodometric Titration Results and Discussion Oxidation-reduction titration is a kind of volumetric analysis where the titrant used undergoes a redox reaction with the analyte. In this experiment‚ the oxidation of iodide (I-) to produce iodine (I2) is taken into consideration. The use of this concept in a redox titration is called iodometry. Iodimetry‚ on the other hand‚ deals with the

Properties of Gases General Chemistry 1 Lab 5 Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air

3.09 Honors: Here is sample data and how you would do the calculations. Of course‚ you will need to use your data‚ but you can follow along step-by-step. In the lab‚ you must record the following measurements: mass of your empty crucible mass of your crucible and the hydrate (the original chemical) mass of the crucible and chemical after heating(which is the dehydrate) The other two in the data table are calculated (mass of hydrate and mass of dehydrate) SAMPLE DATA – YOU MUST USE YOUR

Chapman et.al (2009) studied the local impact of hoisted point sources on late spring aerosol driving and cloud-aerosol cooperations‚ in northeastern North America‚ was studied by utilizing the WRF-Chem community model. The immediate impacts of mist concentrates on approaching sun powered radiation were recreated utilizing existing modules to relate aerosol sizes and chemical composition to airborne optical properties. Direct impacts were reenacted by including a prognostic treatment of cloud bead

Lab experiment 12 Percent of water in a hydrate The goal of Experiment 12 was to learn how to calculate the percent of water (by mass) in barium chloride and an unknown hydrate salt‚ as well as properly calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and
