Quantitative Analysis of Soda Ash by Double Indicator Method
Mark Steven R. Santiago and Kristiene B. Sadiwa Institute of Chemistry, University of the Philippines, Diliman, Quezon City 1101 Philippines Date/s Performed: July 13, 2012; Date Submitted: July 19, 2012 Results and Discussions A mixture of carbonate (CO32), bicarbonate, (HCO32) and hydroxide (OH) ions can be analysed and determined by titration with strong standard acid solution. Volumetric titrimetry can be employed to compute percent compositions of sodium carbonate (Na2CO3), sodium bicarbonate (NaHCO3), and sodium hydroxide (NaOH) in a soda ash sample through the application of neutralization concepts and titrimetric analyses. Volumetric titrimetry has been utilized in …show more content…

Quantitative Analysis by Spectrophotometric Methods
2206 Words  9 PagesAbstract In this experiment, the absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1, in order to determine the maximum absorbance wavelength of KMnO4, we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm, and plotted the λ and A points; the λmax was 530nm. In part 2, the effect of concentration on the absorbance was examined. We prepared…

Quantitative Analysis of Soda Ash by Double Indicator Method
1942 Words  8 PagesQuantitative Analysis of Soda Ash by Double Indicator Method Results and Discussion The experiment focuses in the use of double indicator titration in quantitative analysis of soda ash sample. Titration refers to the process of measuring the volume of titrant required to reach the equivalnece point. This method of analysis, is based on the chemical reaction aA + bB → products (1) where a is the molecules of the unknown substances to be analyzed or the analyte. Analyte reacts with b molecules…

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…

Analysis of Soda Ash and CarbonateBicarbonate Mixture
1703 Words  7 PagesAnalysis of Soda Ash and CarbonateBicarbonate Mixture Submitted: February 27, 2013 Department of Chemical Engineering, Faculty of Engineering University of Santo Tomas España, Manila Abstract A standard acid solution like HCl can be used as titrant for the analysis of both soda ash and a carbonatebicarbonate mixture. In the analysis of soda ash, the volume needed to neutralize the soda ash is used to compute for its alkalinity, in this experiment we obtained a 17.6 % alkalinity with an error…

Statistical Analysis And Quantitative Methods
836 Words  4 Pagesthis course was very helpful in expanding my knowledge pertaining to statistical analysis and quantitative methods. Although I had some knowledge going into this semester from prior classes, I felt uneasy about statistical analysis and its applications. There were so many elements I had questions about and a variety of factors I wished to understand but that were unclear. Specifically, advanced statistical methods seemed to be shrouded in mystery – complex, indecipherable, abstract, and inaccessible…

Qualitative vs. Quantitative Analysis: Evaluating Scientific Methods
642 Words  3 Pagesthe scientific method. The term scientific method refers to a way of investigation or the acquisition of knowledge through the testing of a theory or hypothesis, then working through measurements (observation and empirical notes) to come up with a result, which should prove or disprove the original theory (Johnson & Christensen, 2009; Cary, 2008). Within most environments, there are several basic issues that can be studied either quantitatively or qualitatively, or with a mixed method. There is no…
