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

A Comparison of Gravimetric Analysis and Volumetric Analysis To analysis the proportion of an element in a certain substance‚ the experiment could be done by gravimetric analysis and volumetric analysis‚ and these two methods of analysing could be occupied on several different purpose of experiments as well. In a specific experimental condition‚ there will be one method that is the most suitable to choose‚ and it is depending on the temperature‚ substance status‚ pressure and chemical properties

Quantitative and Qualitative analysis Ensuring accuracy in both quantitative and qualitative methods. Accurate data collection is essential in maintaining the integrity of research. Working accurately greatly decreases the possibility of an error occurring in an experiment‚ provides a greater chance of producing expected results and provides knowledge gained only from proven results. Quantitative methods generate numerical data or data that can be transformed into useable statistics. It is used

Analysis of Commercial Bleach AP Chemistry Introduction: Many commercial products are effective because they contain oxidizing agents. Some products that contain oxidizing agents are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution (remember this from your “funky redox rxns”?)

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any

Food Analysis * Concerned with development of criteria of quality and identity… * Process in w/c sample is treated in a series of steps Importance: 1. It’s necessary in the dev’t and enforcement in standard of identity‚ purity and feel of processed food products. 2. It can provide studies design to improve and control the quality of natural processed food. 3. Can help in the determination of the composition of products in their normal and abnormal storage conditions. Methods

Soda Ash Analysis and Volumetric Analysis of a Carbonate-Bicarbonate Mixture De Guzman‚ Danica Justine R. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila Abstract Titration is a laboratory method in which the endpoint of a reaction is determined quantitatively. In this experiment‚ the amount of soda ash present in a sample was determined and the alkalinity reported as it was titrated using HCl as the titrant. Also‚ the percentage

Synthesis and Analysis of the Coordination Compound Pentaaminechlorideocobalt (III) Chloride Heaven Lin and Forest Lin W.M. Keck Science Department‚ Claremont McKenna‚ Pitzer‚ and Scripps Colleges 925 N. Mills Avenue‚ Claremont‚ California 91711 Abstract Through using the spectrometer and titrations‚ the amount of the coordination compound‚ pentaaminechloridocobalt (III) chloride‚ was determined through a synthesis through an oxidation reduction of cobalt (II) chloride hexahydrate (CoCl2·6H2O)

Analysis of a Commercial Bleach Purpose: The purpose of this lab is to determine the amount of sodium hypochlorite (NaClO) in commercial bleach. This can be done by forming triiodide ions. To make the measurement more accurate‚ starch was added to help determine the endpoint of the solution. The significance of this lab is that industry can use these techniques to determine the amount of NaClO in the bleach of the rival industry and improve it. Hypothesis: The hypothesis is that‚ an accurate
