Consider the system produced by thoroughly mixing 0.50 mol CaCO3(s) with 1.0 L of 1.0 M (H4N)2SO4. By appropriate K, MB, and CB analysis, calculate system pH and the amount of CaCO3(s) remaining on establishment of EQ. Show all pertinent work except arithmetic. (Assume a constant liquid-phase volume of 1.0 L.)
