Chemistry lab report Aim- to determine then enthalpy of neutralization for 1. HCl +NaOH 2. CH3COOH +NaOH 3. 1/2H2SO4 +NaOH And state the trends in the enthalpy of neutralization for acids. Hypothesis- The enthalpy of neutralization is the heat produced when an acid and a mole react together to form one mole of water. Strong acids completely dissociate in water. Weak acids on the other hand partially dissociate in water. Thus a certain amount of the energy evolved, in reacting a weak acid with a base, is used up in ionizing the unionized molecules. Hence the enthalpy of neutralization should be more for the stronger acids and lesser for the weak acids. Thus the enthalpy of neutralization will be more for hydrochloric acid and sulphuric acid, which are stronger acids and lesser for ethanoic acid, which is a weak acid. The hydrogen ion from the acid and the hydroxide ion from the base react to form the...
