Question 1

What is the standard enthalpy of neutralization?

  • The heat absorbed when mixing any two substances
  • The enthalpy change when an acid and base form one mole of water
  • The energy required to dissociate a strong acid

💡 Hint: Think about what happens in an acid-base reaction.

Question 2

ΔH_neut° is usually approximately -57.3 kJ/mol for what type of reactions?

  • True
  • False

💡 Hint: Consider common strong acids and bases used in class.

Challenge Problems

Push your limits with challenges.

Question 1

Calculate the enthalpy change for a reaction where 0.25 mol of hydrochloric acid is neutralized by sodium hydroxide, given that ΔH_neut° is -57.3 kJ/mol.

💡 Hint: Use the relationship between moles and ΔH_neut°.

Question 2

Discuss how the temperature of the solution might change if a weak acid is used instead of a strong acid. What implications does this have for the enthalpy change?

💡 Hint: Remember the differences between strong and weak acids!
