Enthalpy Of Solution Lab Report Assessed on: * Data Collection and Processing (DCP) * Conclusion and Evaluation (CE)

Enthalpy Of SolutionIntroductionAimThe aim of this investigation was to determine the henry of the reply created when disintegration Sodium hydroxide (NaOH) in piddle (H2O). TheoryWhen a immobile ionic change is dissolved in piddle a replace of enthalpy is involved. The enthalpy of a solution, ?Hsol is the enthalpy change when one mole of the substance is dissolved in water to realize aqueous solution. ChemicalSodium hydrated oxide (NaOH)ProcedureThe recommended amount of compound ito habituate is around 0.1 moles. Add water into your caleriometerAdd the solid brininess and influence the mixture thoroughly and continuously. Calculate ?Hsol. Ignore the rut capacitor of the caleriometer.

This was a qualified guess based on that it started to sparkle and looked like it was melting. Another one that probably did scratch the results was the fact that the containers in which we mixed the water (H2O) and Sodium Hydroxide (NaOH) in had holes.

And this increases the energy lost to the surroundings in the bring in of vex, which affects the temperature. Processed DataCalculationsTheory states:?H= -Q/nQ = m * c * ?TWhere in this sham character m = mass of water, c = specific heat readiness of water and T in Kelvin. I n narrate to come whether mass should be i! n kg or g we look at the c-value. c= 4.18 JK-1g-1. And Q is measured in Joules. J = g * JK-1g-1 * K. m must be in grams since J=J, and not J = kJ like it would have been with kg. We feces charter that...
