Write out a detailed procedure for determining the enthalpy of reaction between citric acid (H3Cit) and sodium hydroxide (NaOH). Note that the neutralization reaction is:
H3Cit + 3 NaOH => NaCit + 3 H2O
Be sure to calculate what volume of each .50 M solution should be mixed to give a total volume of 50.0 mL and the reactants in the correct stoichiometry.
Introduction to the Nernst Equation Learning Goal: To learn how to use the Nernst equation. The standard reduction potentials listed in any reference table are only valid at standard-state conditions of 25 circ C and 1 M. To calculate the cell pot..
