WebIn Part A, the reaction involved HCl, a strong acid, and NaOH, a strong base. The calculated enthalpy per mole of H + is 57800J/mol or 57k.8kJ/mol. This value can be interpreted as the number of Joules required to neutralize 1 mole of H +.As the procedure required the enthalpy to use the heat evolved (positive), the enthalpy per mole of H + … WebJul 22, 2014 · When 25.0 mL of 0.700 mol/L NaOH was mixed in a calorimeter with 25.0 mL of 0.700 mol/L HCl, both initially at 20.0 °C, the temperature increased to 22.1 °C. The …
Why are neutralisations involving weak acids and bases less exothermic …
