Enthalpy of Neutralization Introduction Energy changes always accompany chemical reactions. If energy‚ in the form of heat‚ is liberated the reaction is exothermic and if energy is absorbed the reaction is endothermic. Thermochemistry is concerned with the measurement of the amount of heat evolved or absorbed. The heat (or enthalpy) of neutralization (∆H) is the heat evolved when an acid and a base react to form a salt plus water. Eq. 1 HNO2(aq) + NAOH(aq) → NaNO2(aq) + H2O(l) + Q Q in the

Lecture 12 Chapter 6 6.1 Thermochemistry: Energy & units (p.227) From observation we know‚ that - some chemical reactions begin as soon as the reactants come into contact with each other (precipitation reactions) - some reactions are slow or even so slow at room temperature that even lifetime is not enough to observe a measurable change (rusting of iron‚ tarnishing silver) Also‚ almost all chemical reactions involve exchange of heat (or energy): in combustion reactions
