Unformatted text preview: room temperature. How much water can he add before he gets into trouble. (trouble = If the solution reaches the boiling point of water (212 o F) additional water added to the system will boil and splash sulfuric acid ) [use the H-x diagram handed out in Lecture 22] His lab mate uses a different approach. She plans to mix both solutions (100g water and 100g conc. H 2 SO 4 ) by adding the acid to the water while cooling the solution in a surrounding ice bath. How much ice does she need to return the acid solution to room temperature after mixing? (assume that the cooling is only due to latent heat changes in the ice (i.e. melting)) The properties the cooling water / ice are: ∆ H fusion = 333 J/g ∆ H vaporization = 2260 J/g 1BTU = 1055 J 1 lbm = 453.4 g...
