SUMMARY

The discussion focuses on calculating the enthalpy of solution for sulfuric acid (H2SO4) in water at 30°C for concentrations of 0.2, 0.5, and 1 mol/kg. A participant attempted to utilize an enthalpy-concentration diagram but faced difficulties in interpretation. The relevant resource provided is a PDF document from NorFalco that contains necessary data for the calculation. The goal is to determine the theoretical enthalpy of solution to compare with experimental results.

PREREQUISITES
  • Understanding of enthalpy and thermodynamic principles
  • Familiarity with sulfuric acid (H2SO4) properties
  • Ability to interpret enthalpy-concentration diagrams
  • Basic knowledge of solution concentration calculations
NEXT STEPS
  • Review the enthalpy-concentration diagram for sulfuric acid solutions
  • Study the enthalpy of solution calculations for strong acids
  • Examine the PDF document from NorFalco for specific data
  • Learn about experimental methods for measuring enthalpy changes in solutions
USEFUL FOR

Chemistry students, researchers in thermodynamics, and laboratory technicians involved in acid-base reactions and solution chemistry will benefit from this discussion.

Homework Statement



How can I calculate the enthalpy of solution for sulfuric acid at 30°C/68°F, for 0,2;0,5;1 mol/kg?

Homework Equations





The Attempt at a Solution


I tried using a enthalpy-concentration diagram, but I cannot read it. I would apreciate if anyone could help me!
 
Physics news on Phys.org
what is this diagram you have? what data are you provided with?
 
This one: http://docs.google.com/gview?a=v&q=cache:sexRAoFSlI4J:www.norfalco.com/documents/NorFalco_H2SO4Property07.pdf+calculate+enthalpy+sulfuric+acid&hl=en&gl=br

The only data I got is the concentration of the solution H2SO4 and water. I needed to find the theoretical enthalpy of solution for this reaction, to compare with the results I got from the experiment.
