Which of the following is required in an experiment to determine the enthalpy of solution of anhydrous CuSO? l. Mass of the anhydrous CuSO 4 II. Volume of w...

Answer Details

To determine the enthalpy of solution of anhydrous CuSO₄, we need to dissolve a known mass of CuSO₄ in a known volume of water, measure the initial temperature of the water and the final temperature of the solution. Therefore, we need all the four options: i.e., l, ll, lll, and IV. We need to know the mass of CuSO₄ used to determine the amount of solute in the solution. The volume of water is required to calculate the concentration of the solution. The initial temperature of the water is required to determine the amount of heat absorbed by the solution, and the final temperature of the solution is required to determine the amount of heat released by the solution.
