4. An experiment is to be performed to determine the standard molar enthalpy of neutralization of a strong acid by a strong base. Standard school laboratory equipment and a supply of standardized 1.00 mol/L HCl and standardized 1.00 mol/L NaOH are available. a. What equipment would be needed? List them. b. What measurements should be taken? List them. c. Without performing calculations, briefly describe how the resulting data should be used to obtain the standard molar enthalpy of neutralization. d. When a class of students performed this experiment, the average of the results was -55.0 kJ/mol. The accepted value for the standard molar enthalpy of neutralization of a strong acid by a strong base is -57.7 kilojoules per mole. Briefly describe two likely sources of experimental error that could account for the result obtained by the class. Mistakes, blunders, or miscalculations are not types of experimental error.
