Sulfuric acid is used in the synthesis and processing of many chemicals and metals, and it is the electrolyte in common lead-acid batteries. It is used in various strengths, ranging from concentrated (100\%) to dilute; so being able to estimate its concentration from a simple measurement of specific gravity is quite useful. Suppose you prepare a solution that is 5.00wt%H2SO4 in water and intend to confirm the concentration by comparing the specific gravity of the solution to that available from the literature. To 95.0g of water you carefully add 5.00g of H2SO4 and allow the resulting mixture to equilibrate at 20C. (You know that rapidly adding the acid to water or water to concentrated acid can both lead to dangerous splatters of liquid.) Physical Property Tables Volume Additivity From the component specific gravities, estimate the volumes of water and sulfuric acid that have been blended. Vwater=mL Vsulfuricacid=mL Estimate the density of the 5.00wt% sulfuric acid assuming that the volumes are additive. Perry's Chemical Engineer's Handbook lists the specific gravity of sulfuric acid as a function of both acid concentration and temperature. The value for 5.00wt% sulfuric acid at 20C is listed as 1.0317. Estimate the volume of the 5.00wt% sulfuric acid solution prepared as described by the above process. mL Attempts: 0 of 3 used Required Volume of Acid Estimate the volume of 40.0wt% sulfuric acid (SG =1.2991 at 25C ) that must be added to the 100.0g of the 5.00 -wt\% solution to produce a solution that is 35.0wt% sulfuric acid? mL Attempts: 0 of 3 used Sulfuric acid is used in the synthesis and processing of many chemicals and metals, and it is the electrolyte in common lead-acid batteries.
