Suppose you prepare a solution that is 30 wt% h2so4 in water and intend to confirm the concentration by comparing the specific gravity (sg) to a value obtained from the literature. you slowly added 30 g h2so4 to 70 g h2o and allowed the resulting mixture to equilibrate at 20oc. i). estimate the volumes of h2o and acid that were blended and estimate the density of the 30 wt% acid solution assuming volume additivity. ii). if the handbook sg value of the 30 wt% acid is given as 1.2185, estimate the volume of 30 wt% acid prepared as above. iii). what volume of 40 wt% acid (sg = 1.2991) must be added to 100 g of the 30 wt% solution to produce a solution that is 35 wt% h2so4?
