When a solid dissolves in water, the solution may become hotter or colder. The dissolution enthalpy (dissolving) can be determined using a coffee cup calorimeter. In the laboratorv a general chemistry student finds that when 1.89 g CaBr2(s) is dissolved in 101.10 g water, the temperature of the solution increases from 24.47 to 26.81 °C Thermometer Cardboard or Styrofoam lid The heat capacitv of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to...
