This experiment MUST be carried out in the hood. When HCl is mixed with CaCO 3 chips, the spontaneous reaction that ensues produces carbon dioxide gas. Hydrochloric acid may cause severe burns. Hydrochloric acid vapors are extremely irritating to the skin, eyes, and respiratory system. It can irritate the skin and eyes.
Sodium hydroxide can cause severe burns of the eyes and skin.
Dust from solid sodium hydroxide is very caustic. Acetone is very flammable. Care must be taken to prevent the diffusion of flammable vapors before igniting the acetone in the beaker. Production Of Carbon Dioxide Gas Place 20 g CaCO 3 chips into a 500-mL filter flask. Attach the 90-cm piece of rubber tubing to the sidearm of the flask.
