3) When potassium chloride reacts with oxygen under the right conditions, potassium chlorate is formed: 2 KCl + 3 O2 ( 2KClO3. Given that the heat of formation of potassium chloride is –436 kJ/mol and the heat of formation of potassium chlorate is –391 kJ/mol, determine the heat of reaction. Calorimetry Practice Worksheet

a) Add a small scoop of baking soda, sodium bicarbonate, to a test tube and add water to height of about 1 centimeter. Stir. b) Add a few drops of silver nitrate solution to the baking soda solution. c) In another test tube place the same amount of baking soda and dissolve as above. Add hydrochloric acid. CAUTION: ACID CAN CAUSE SEVERE BURNS.

(b) Solubility of a substance in water at a given temperature Put about 50 cm3 of water in a beaker and add baking powder, sodium bicarbonate, gradually while stirring. Potassium sulphate is an alternative substance. Make a saturated solution by stirring until no more solute will dissolve. Read the temperature of the saturated solution.

“Or, throw some baking soda into the pan. That’s baking soda—noncombustible. Don’t use flour or powdered creamer, as both are flammable. Baking soda smothers flames by blocking oxygen’s access to the grease. Even better, baking soda is sodium bicarbonate (NaHCO3), which, when heated, releases carbon dioxide gas (NaHCO3 ( NaOH + CO2 (g)).

Sodium bicarbonate (baking soda) Boiling water. Large beaker. Tongs. Demonstration: Simply wrap the tarnished piece of silver from demonstration #1 in aluminum foil and add a few teaspoons of baking soda and place in a beaker containing boiling water for a few minutes (the rate will depend on the extent of tarnishing and the quality of the silver).
