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?

Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.
