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 inflame content of the theme created when disintegration Sodium hydroxide (NaOH) in piddle (H2O). TheoryWhen a immobile ionic merge 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 sodium chloride and influence the mixture thoroughly and continuously. Calculate ?Hsol. Ignore the inflame 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 imprint 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 form of heat, which affects the temperature. Processed DataCalculationsTheory states:?H= -Q/nQ = m * c * ?TWhere in this mistaken character m = mass of water, c = speci fic heat readiness of water and T in Kelvin! . In fellowship to come whether mass should be in 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 push aside charter that...
