Purpose: Observe the properties of carbon dioxide. Discover what happens when carbon dioxide mixes with water. Record a neutralization reaction
Materials: Dry ice, universal indicator, sodium hydroxide, water. Caution: ice is -73 celsius and may cause skin damage if it is touched. Sodium hydroxide is corrosive. Universal indicator is poisonous. Use appropriate eyewear. Wash hands with soap after the lab is over.
Procedure: Follow the procedure and write your observations:
Properties of carbon dioxide:
1. Place a nugget of ice on the table and bat it around with your hands. It'll start to slide around
2. Place a nugget of ice on the table and put a coin on it. Breathe on the coin.
3. Place a nugget of ice in a puddle of water
4. Rate of Reaction: Put ice in a flask of cold water. Now use hot water.
5. Neutralization: Put on your goggles: place a dropperful of sodium hydroxide in a flask of water and another dropperful of universal indicator. Drop a nugget of ice in the water. Observe the reaction.
Conclusions: write down your conclusions on the properties of Carbon Dioxide.
