WebA large amount of energy is required to ionize HCN. How to Calculate Heat of Neutralization. Suppose specific volumes of the acid and base react in a calorimeter and liberate heat. The heat gained by the resultant solution can be calculated using the following formula [4]: Q soln = mcΔT. Where. Q: Heat of the resultant solution WebHeat of Neutralization: HCl (aq) + NaOH (aq) Equal volumes, 50.0 mL, of 3.0 M hydrochloric acid and 3.0 M sodium hydroxide solutions having an initial temperature of 20.0°C react in a calorimeter. The resultant solution …
