A coffee cup calorimeter is used to determine the heat of reaction of a precipitation reaction. 155.0 mL of a 0.150 M iron (III) chloride solution is added to the coffee cup and a thermometer is placed in the solution. The initial temperature is recorded as 23.0 ℃. 75.0 mL of a 0.250 M potassium hydroxide solution is added to the cup and mixed. The temperature rises to 26.5 ℃. (Assume the volumes are additive and also assume the specific heat of the solution is 4.18 J/g℃ and the density of the solution is 1.0 g/mL)
Write the full balanced chemical reaction and show all the work needed to determine the heat of reaction (ΔH). Be sure to include an explanation of how the energy transferred to or from the solution is equal to the energy transferred to or from the reaction (conservation of energy)
Write the net ionic equation for the precipitate that formed. How many grams of precipitate will be produced? What is the concentration of each of the ions in the solution after the reaction?
