1) How would the temperature change and the calculated heat of neutralization vary if the
volumes remained the same but the concentrations of the acid and the base were
doubled? Explain.
2) How would the temperature change and the calculated heat of neutralization vary if the
concentrations remained the same but the volume of the acid and base was cut in half?
Explain.

Answer:

1) The standard enthalpy change of neutralization is the enthalpy change when solutions of an acid and an alkali react together under standard conditions to produce 1 mole of water. Notice that enthalpy change of neutralization is always measured per mole of water formed. Enthalpy changes of neutralization are always negative - heat is released when an acid and and alkali react. For reactions involving strong acids and alkalis, the values are always very closely similar, with values between -57 and -58 kJ mol-1. That varies slightly depending on the acid-alkali combination (and also on what source you look it up in!).
