The results are summarised as follows:<br>1. The chemical formula of Calcium sulphite was found to be CaSO<sub>2</sub>⋅1/2 H<sub>2</sub>O.<br>2. The heat of oxidation of crystalline and amorphous CaSO<sub>3</sub>⋅1/2 H<sub>2</sub>O are 60.51 kcal/mol and 62.95 kcal/mol respectively.<br>3. Crystalline calcium magnesium sulphite was discovered and its chemical formula was determined to be CaMg(SO<sub>3</sub>)<sub>2</sub>⋅7H<sub>2</sub>O.<br>4. The dehydration temperature of crystalline and amorphous CaSO<sub>3</sub>⋅1/2 H<sub>2</sub>O are 400°C and 375°C respectively. The compound CaMg(SO<sub>3</sub>)<sub>2</sub>⋅7H<sub>2</sub>O dehydrates stepwise at 110°C and 200°C.<br>5. The calcium sulphite when suspended in water is easely oxidized with air bubbles to good gypsum crystals.
