5. Derive equations and draw diagrams. (20 pts) a) Proton balance equation, charge balance equation and mass balance equation in the water system. i) Monoprotic acid: CH3COOHH++CH3COO ii) Diprotic acid: H2CO32H++CO32 and or H2CO3H++HCO3 b) Draw pH-pC diagram of CH3COOH at 25C using an Excel file. Ka(at25C ) of CH3COOH=1047 and 1.0M of CH3COOH was added to the pure water, pH,log[H+],log[OH]log[CH3COOO]and log[CH3COOH] should be shown in the graph. In addition, show how you derive pH,[H+],[OH] [CH3COO]and [CH3COOH] as a function of [H+]. The range of pH(x-axis) is 1 through 14 that of pC is 0 through 14. Submit both the Excel table and the pHpC diagram
