Abstract

The heat of oxidation of aqueous sulfur dioxide with gaseous chlorine has been determined by calorimetric methods. The results correspond to the reaction: $\begin{matrix} {Cl}_{2} (g) + {SO}_{2} \cdot 2500 H_{2} O + 2502 H_{2} O = H_{2} {SO}_{4} \cdot 2500 H_{2} O + 2 (HCl \cdot 1250 H_{2} O), \\ Δ H (25 ° C) = - 77.28 \pm 0.14 kcal / mole . \end{matrix}$ The heat of formation of aqueous sulfuric acid (in 2500 moles of water) has been calculated to be -213.92 kcal/mole.

二氧化硫水溶液与气态氯的氧化热。

用量热法测定了二氧化硫水溶液与气态氯的氧化热。结果与以下反应相符 Cl 2 ( g ) + SO 2 ⋅ 2500 H 2 O + 2502 H 2 O = H 2 SO 4 ⋅ 2500 H 2 O + 2 ( HCl ⋅ 1250 H 2 O ) , Δ H ( 25 ° C ) = - 77.28 ± 0.14 千卡/摩尔。经计算，硫酸水溶液（在 2500 摩尔水中）的形成热为-213.92 千卡/摩尔。
