Heat of Neutralization from Temperature Rise Calculator

Q = m · c · ΔT and ΔH_neut = −Q / n_water.

Compute the molar heat of neutralization ΔH_neut for a strong acid + strong base reaction from a coffee-cup calorimetry temperature rise. The heat absorbed by the solution Q = m_solution · c · ΔT (treating dilute aqueous solution like water, c ≈ 4.18 J g⁻¹ °C⁻¹), then ΔH = −Q / n_water_formed (kJ/mol).
