A beaker contains deionized water, and simultaneously 0.10 mol Na2O(s), 0.050 mol Na2S(s), 0.040 mol H4NHSO4(s), 0.15 mol (H4N)2SO4(s), and 0.050 mol (HO)2SO2(l) (H2SO4) is added to the beaker. The student then adds more water until the solution volume becomes 1.0 L Write the eqn for each large-extent B/L A/B rxn which occurred on making this mixture. Do this by starting with the rxn that involves the strongest B/L A with the strongest B/L B. Label this rxn (i). Continue writing eqns in this "strength order" until all eqns have been written.
