Objectives
The main purpose of this experiment includes determining reaction heat for solid KOH dissolution;
determining heat reaction for solid KOH in aqueous HCl; determining reaction heat for aqueous KOH in
aqueous HCl; and using Hess’ Law to make comparison of additive reaction heats.
Introduction
This experimental study uses Styrofoam cup to measure the heat discharge by three dissimilar
reactions. The two reaction are express as one. Thus, the reaction heat of the final reaction is the same as
the sum of the two heat reactions. In some instances, the concept is referred to as heat reaction additivity
or Hess’s Law.
Equipment and Materials
The materials and equipment used in this experiment include pH paper, watch glass, 250 mL
beakers, 50 mL beaker, Thermistor, glass stirring rod, graduated cylinder, Styrofoam cup, 1.5 M HCl
solution, and solid KOH.
Procedure
The procedure for this experiment involves three parts as follows:
Part I: KOH(s) ➞ KOH(aq)
This part involves recording the mass of a 50 mL beaker when it is dry and clean, and measuring
mass of the beaker with 2-3 grams KOH pellets. The thermistor is use to temperature and time recorded;
100 mL of water is added to a graduated cylinder and temperature measured for about 2 minutes; the
