Noah Stewart-Maddox Chem 121 10/12/11 Synthesis of Potassium Ferric Oxalate Trihydrate and The Determination of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In

The present work investigates the mechanical properties and tribological behavior of Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite

296 HANDOUT: CONTINUOUS FLOW (PRODUCT ORIENTED LAYOUT) AND BOTTLENECK ANALYSIS Reference: Operations Management by Mark A. Vonderembse and Gregory P. White. The Product Layout and System Capacity The capacity of a product-oriented system can be visualized as a series of pipes of varying capacity‚ with the smallest diameter or capacity holding back the entire system. Exhibit 9.3 illustrates five pipes (departments or machines) with different diameters (capacities). The output

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

adding additional mass. Ex. The iron filings having some sand particles leftover. A yield under 100% would mean that some of the substance was not recovered‚ it could have been lost (spilled) or found in another substance (not separated completely). The percent yields may give some insight into what occurred during the procedure. For example if the percent of iron is >100‚ but the percent of sand is <100 then it may show that some sand was not separated from the iron‚ and was measured with that material

The uncommonly known Bessemer process sparked a turning point in the 1850’s. A process designed to yield steel at a much faster rate allowed for a development in traditional structures‒bridges‚ buildings‚ and skyscrapers‒as well as advanced economic theory and practices and their relation to a successful business model. Revolutionaries such as Andrew Carnegie (a successful entrepreneur) and James Buchanan Eads (an engineer specializing in bridges) paved the way for practices and techniques still

number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the piece galvanized iron into a 400-ml beaker 4. Added 25mL of hydrochloric acid
