Calculate the theoretical amount of .5M NaOH that it would take to neutralize approx. 2.0 g KHP. KHP is a monoprotic acid, the molar mass of KHP is 204.22 g/mol and the molar mass of NaOH is 40.00 g/mol. Answer in terms of mL. I converted g KHP to mols,

2. Sulfuric acid comes from the oxidation of sulfur. The stages of the reactions are given below: S + O2 --> SO2 ∆H= -296.8 kj SO2 + 1/2 O2 --> SO3 ∆H= -98.9 kj SO3 + H2O --> H2SO4 ∆H= -130.0 kj The typical plant produces 750 tons of H2SO4 per day.
