An acid-base neutralization reaction is exothermic for the, Ask an Expert

Academics

An acid-base neutralization reaction is exothermic. For the measurement of the enthalpy of neutralization, the change in Hn(n is suppose to be a subscript), for the reaction, heat is inevitably lost to the calorimeter (beaker or styrofoam cup). How will the unaccounted for heat loss affect the reported value for the enthalpy of neutralization for the reaction
