How will forgetting to start recording the temperature until after adding the HCL to the NaOH in the calorimeter affect the determination of the enthalpy of neutralization?Why is the enthalpy of neutralization for all strong acid-strong base reaction the same within experimental error? Is this also the case for all weak acid-strong base reactions?
