Push your limits with advanced challenges
If you mix 25 mL of 1 M H₂SO₄ with 25 mL of 1 M NaOH and the temperature changes from 25°C to 35°C, calculate ΔH_neut°. Assume the final volume is 50 mL and the specific heat capacity of the solution is the same as water. Show your work.
💡 Hint: Pay attention to how you're calculating the amount of moles and the heat involved.
Describe a calorimetry experiment that measures the enthalpy of neutralization of acetic acid with sodium hydroxide, and predict what changes you would observe.
💡 Hint: Remember about the products formed and how the temperature indicates heat release.
