Question- A 20 wt% solution of sulfuric acid in water is to be enriched to a 60 wt% sulfuric acid solution by adding pure sulfuric acid.
(a) How much pure sulfuric acid should be added?
(b) If the 20 wt% solution is available at 5 °C, and the pure sulfuric acid at 50°C, how much heat will have to be removed to produce the 60 wt% solutions at 70°C?
