WebAug 27, 2024 · Hello everyone, I have this exercise: "The neutralization heat of HCl by NaOH is ΔH°r = -56.2 kJ / mol. How much heat is released when 125 mL of 1,750 M HCl is mixed with 195 mL of 0.667 M NaOH?" WebFor weak acids or bases, the heat of neutralization is pH-dependent. [1] In the absence of any added mineral acid or alkali, some heat is required for complete dissociation. The total heat evolved during neutralization will be smaller. e.g. at 25°C The heat of ionization for this reaction is equal to (–12 + 57.3) = 45.3 kJ/mol at 25 °C. [2]
