A 12.0-molar solution of sodium hydroxide (SG = 1.37) is neutralized with 75.0 mL of a 4.0 molar solution of sulfuric acid (SG = 1.23) in a well-insulated container.
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 — 1.17kJ/mol, and the energy balance reduces to
- for this constant-pressure batch process.
