A 10 mol% aqueous sulfuric acid solution (SG = 1.27) is to be titrated to neutrality at 25 °C with a 3 molar caustic soda (NaOH) solution (SG = 1.13): H24 () + 2H() → 24 () + 2H2() (a) Calculate the required volume ratio (cm3 caustic solution/cm3 acid solution). (b) Calculate the standard heats of formation (kJ/mol solute) of each of the three solutions involved in this process, and the heat released (kJ/cm3 acid solution neutralized) if the reactants and products are all at 25 °C. The heat of solution of sodium sulfate is -1.17 kJ/mol. Assume that Q = ΔH for the process.
