When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 9.66 g of NaCIO4(s) are dissolved in 119.20 g of water, the temperature of the solution drops from 22.60 to 20.11 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.68 1/°C. Based on the student's observation, calculate the enthalpy of dissolution of NaClO4(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. AH dissolution kJ/mol Thermometer Cardboard or Styrofoam lid Nested Styrofoam cups Reaction occurs in solution.
