A 12.0-molar solution of sodium hydroxide (SG = 1.37) is neutralized with 75.0mL of a 4.0 molar solution of sulfuric acid (SG = 1.23) in a well-insulated container.

(a) Estimate the volume of the sodium hydroxide solution and the final solution temperature if both feed solutions are at 25°C. The heat capacity of the product solution may be taken to be that of pure liquid water, the standard heat of solution of sodium sulfate is – 1.17 kJ/mol, and the energy balance reduces to Q = ΔH for this constant-pressure batch process.

(b) List several additional assumptions you made to arrive at your estimated volume and temperature.
