I was trying to determine the standard enthaply change of neutralization for H2SO4 and NaOH. In my reaction 58 cm3 of H2SO4 , c=(1,80 mol/dm3) reacted with 1dm3 NaOH c=0,162mol/dm3. That means that 0,104 mol of H2SO4 reacted with 0,162 mol of NaOH. In my experiment I calculated standard enthaply change of neutralization and my result was -67241,79 J/mol. If i understand correctly my result should have been around -55.8 kJ/mol.
I would like to know what could have affected my result?
We used tehnicqe of calorimetry.
