Calculate the bicarbonate and carbonate alkalinities, in mg/L as CaCO3, of the water described in the following mineral analysis for a water sample taken from Well No. 1 at the Eastwood Manor Subdivision near McHenry, Illinois, USA. (Based on total alkalinity and pH values, equation for calculation of bicarbonate and carbonate alkalinities from total alkalinity and pH, Topic 04 Softening, see below) (4 marks) e: All reported ion concentration as mg/L unless stated otherwise, temperature at 25C. HCO3=1+([H+]2K2)50,000{(50,000A)+[H+]([H+]KW)}CO32=([H+]2K2)(HCO3) Spring 2023 Determine the total, carbonate, and noncarbonate hardness in mg/L as CaCO3 for the water analysis in Problem 2 using the predominant polyvalent cations (Ca2+ and Mg2+). (4 marks) Calculate the total, carbonate, and noncarbonate hardness for the water analysis in Problem 3 in mg/L as CaCO3 using all the polyvalent cations. What is the percent error in using only the predominant cations as in Problem 3
