Experiment # 4: Analysis of Soda Ash Experiment # 5: Volumetric Analysis of a Carbonate – Bicarbonate Mixture Submitted by: Eugenio December 2012 Department of Chemical Engineering University of Santo Tomas España‚ Manila Abstract Soda ash is the common name for sodium carbonate (NaCO3)‚ a chemical salt derived from carbonic acid. It is frequently used in manufacturing‚ industry‚ and in domestic chores. Glass production is one of the primary industrial uses for sodium carbonate. It is also

my experiment If I was to improve my experiment I could attempt to read the burette to the bottom or top of the meniscus by doing this it might give me accurate results for my experiment. Another way of improving my experiment could be that I use volumetric pipettes for measuring. Calculate the maximum percentage error in the average titre value. Percentage error = maximum error x 100% Value of

Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration

Introduction: The main objective in this experiment is to determine if the claims made by the US government‚ regarding the spectrophotometric analysis of a copper penny hold true. Before 1982‚ the Lincoln cent contained 95% copper and 5% various mixtures of zinc and tin. As the cost of copper increased‚ the cost to produce the penny was more than the actual face value of the penny. This caused the US government to change the composition of the penny. The pennies we know today consist of a copper

I. Objective The first objective of the measurement of thermal conductivity & one-dimensional heat conduction experiment was to identify three different metal specimens by comparing their experimentally determined thermal conductivities to known thermal conductivity values of existing metals. The second objective of the experiment was to establish a connection between the thermal conductivities & temperatures of the metal specimens. Thirdly‚ the contact resistance of the interfaces between

Determination of Vitamin C by an Iodometric Titration Purpose: The goal of this lab is to determine the concentration of vitamin C in juices and Real Lemon. A redox titration‚ involving an iodometric method‚ will be used to do the analysis. The samples will be classified by their Vitamin C content. Introduction: Although most mammals can synthesize vitamin C‚ or ascorbic acid (C6H8O6)‚ from sugars‚ man must ingest considerable quantities of this substance. The National Academy of Sciences recommends
