Write out a detailed procedure for determining the enthalpy of reaction between citric acid and sodium hydroxide. Note that the neutralization reaction is: H3Cit + 3NaOH --> Na3Cit + 3H20. Be sure to calculate what volume of each 0.50M solution should be mixed to give a total volume of 50.0mL and the reactants in the correct stoichiometry.
