Diluting sulfuric acid with water is highly exothermic:
(Use data from the Appendix to find
for diluting 1.00 mol of H2SO4(l)
(d = 1.83 g/mL) to 1 L of 1.00
MH2SO4(aq) (d =
1.060 g/mL). )
Suppose you carry out the dilution in a calorimeter. The initial
T is 22.8°C, and the specific heat capacity of the final
solution is 3.334 J/gK.
What is the final T in °C ?

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 wt% H2SO4 in water and intend to confirm the concentration by comparing the specific gravity of the solution to that...

When a 3.13-g sample of liquid sulfuric acid dissolves in 33.6
g of water in a coffee-cup calorimeter (see above figure) the
temperature rises from 22.00 oC to 41.81 oC.
Calculate H in kJ/mol H2SO4 for
the solution process.
H2SO4(l)
2 H+(aq) + SO42-(aq)
The specific heat of water is 4.18 J/g-K.

Two aqueous sulfuric acid (H2SO4) solutions containing 20.0 wt% H2SO4 (SG=1.139) and 80.0 wt% H2SO4 (SG=1.727) respectively, are mixed to form a 4.00 molar solution (mol/L) (SG=1.213). Calculate the mass fraction of sulfuric acid in the product stream. Atomic weight: H=1g/mol, O=16g/mol, S=32g/mol. Taking 100 kg of the 20 wt% feed solution as a basis, calculate the volumetric feed ratio of 20.0 wt% H2SO4 to 80.0 wt% H2SO4, to 2 decimal places.

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1659 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 11.76 mL of the standard solution. What...

A) Considering the dissociation reaction for sulfuric acid in water, what is the pH of a 1.00 x 10^-2 M solution of H2SO4? B) HSO4- will hydolize in water to produce additional H30+; its Ka = 1.2 x 10^-2. Recalculate the pH of the 1.00 x 10^-2 H2SO4 solution, this time also considering the additional H30+ produced from the reaction.
