Calculate the molar concentrations of oxalic acid (COOH)2, HOOCCO2-, (CO2)22-, H3O+, and OH- in 0.15 M (COOH)2 (aq). This is a special case of general diprotic acid dissociation. First, we need to find the pKa1 and pKa2 in the water at room temperature, which is available online e.g. Wikipedia (oxalic acid). pKa1 = 1.23, pKa2 = 4.19. Either solve numerically or analytically. Report here [H3O+] = ______ M. 2 sig. figures.
The following primary standards can be used for the standardization of bases except. a. Benzoic acid b. Oxalic acid c. CaCO3 d. KHP A solution that may contain NaOH, Na 2CO3, and NaHCO3, alone or in compatible combination was titrated with 0.1200 M HCl. The volume of the acid required to reach the phenolphthalein endpoint was 25.67 mL while 38.13 mL to reach the methyl red endpoint. What are the components of the mixture? a. Na2CO3 only b. NaOH only...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
