Candle Burning Lab
Problem: What are the requirements for and characteristics of a candle flame? What are the products of the combustion of a candle? The purpose of this lab was to find out the properties and characteristics of a candle. Also the purpose was to find the remnants that the combustion of a candle leaves behind as gas. I learned that the candle that is burning releases a certain gas into the air. I also learned that limewater has a chemical reaction when exposed to that gas and turns red.
Hypothesis: For this Lab, my hypothesis was that the candles are going from solid to gas because of a high and quick rise in temperature.
Materials
1. Large birthday candles 2. Matches 3. One used disposable miniature loaf pan
4. 250 ml limewater …show more content…
Solid rubber stopper to fit the flask Procedure
1. Light a candle and allow a drop or two of liquid wax to fall into the center of the pan. Press the candle upright onto the melted wax before it can solidify. If the candle burns too low, repeat this step with a new candle.
2. Observe the flame of the burning candle for a few minutes. Try to observe what if burning and where the burning takes place. Observe the different regions of the flame.
3. Light a second candle and gently blow out the flame of the first candle and move the flame from the second candle into the smoke of the first. Record your observations.
4. Pour tap water into the pan to a depth of about 1 cm.
5. Quickly lower an Erlenmeyer flask over the lit candle so that the mouth of the flask is lower than the water level. Allow the flask to remain in place for approximately one minute. Record your observations.
6. Lift the flask out of the water, turn it upright, and add about 25 ml of limewater. Stopper the flask and swirl the solution for approximately one minute. Record your observations. If the solution becomes cloudy or chalky, calcium carbonate was formed, indicating the presence of carbon dioxide in the flask. Qualitative Data
