WebQuestion: Using the provided data determine the experimental value of AH for the reaction: 3NaOH(aq) + 1H3PO4(aq) → You may assume the density and specific heat capacity of … WebIn determining the mass, m, of the solution use 1.11 g/mL for the density. Use 4.18J/ (g•°C) as the specific heat, Cp, of the solution. q = Cp ´ m ´ ∆T 3. Use the heat energy that you calculated in 2 above to determine the enthalpy change, ∆H, for the reaction in terms of kJ/mol of phosphoric acid. This is your experimental value of ∆H. 4.
