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

1 A Geometric Approach to Strapdown Magnetometer Calibration in Sensor Frame J.F. Vasconcelos‚ Member‚ IEEE‚ G. Elkaim‚ Member‚ IEEE‚ C. Silvestre Member‚ IEEE‚ P. Oliveira Member‚ IEEE‚ and B. Cardeira Member‚ IEEE Abstract In this work a new algorithm is derived for the onboard calibration of three-axis strapdown magnetometers. The proposed calibration method is written in the sensor frame‚ and compensates for the combined effect of all linear time-invariant distortions‚ namely soft

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

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

1 Basics Review and Calibration of Volumetric Glassware There are three types of containers used in lab to contain or deliver liquids: volumetric‚ ordinary‚ and disposable glassware. Volumetric glassware are containers that have been calibrated at a specific temperature to deliver or contain VERY PRECISE amounts of liquid. Examples of volumetric glassware that we will use include burets‚ pipets‚ and volumetric flasks. Ordinary glassware has less precise volume calibrations and are used whenever
