Question
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 20.0 wt% H2SO4 in water and intend to confirm the concentration by comparing the specific
gravity of the solution to that available from the literature.
To 80.0 g of water you carefully add 20.0 g of H2SO4 and allow the resulting mixture to equilibrate at 20°C.
(You know that rapidly adding the acid to water or water to concentrated acid can both lead to dangerous splatters of liquid.)
