2 cards from this section. Quick, good the night before a test.
What is the Standard Enthalpy of Neutralization?
Think about what happens in acid-base reactions.
Name one acid-base reaction that can illustrate ΔH_neut°.
Recall the common school science reactions.
What is the approximate value of ΔH_neut° for strong acid-strong base reactions?
Recall the standard enthalpy value we discussed for neutralization.
True or False: The enthalpy of neutralization varies significantly depending on the acid and base used.
Think about the main products formed in these reactions.
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.
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.
Remember about the products formed and how the temperature indicates heat release.
