Analysis of Soda Ash and Carbonate-Bicarbonate 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 carbonate-bicarbonate 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

at least 29% of Canadian citizens have reported that they have faced family separation and divorce from their parents. Moreover‚ the statistics also showed that the average marriage in Canada only lasted for ten years at most (Urquia et al‚ 2013). A further fifteen percent admitted that separated spouses who shared time among both of them to raise them independently were raising them. The statistics of family separation in Canada are also quite serious because 50% of the people who are married believe

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate
