Put the Calcium Chloride and Sodium Bicarbonate on one side of the bag. Other side of the bag we put Phenol Red and water. Then mixed them and it should turn a yellow color. When you are holding the bag at first it seems like its getting warm but as you continue to shake and mix the bag the colder the feeling of the bag gets. Also the more you shake and mix whats in the bag the bigger the bag got. Some bags might pop open because of all the gases being produced and others just got really inflated. Calcium Cholride makes the bag warmer. Sodium makes the bag inflate. Water helps with the infaltion. Calcium Chloride mixed with the Phenol Red makes the smell.
1. Calcium chloride mixed with water.
2. Calcium Chloride makes it warmer.
3. The overall color was a yellow orange color. Yes.
4. No not always, the bag turned color right away and as you continued to shake and mix the chemicals the temperature changed.
Today my lab patner and I finished up our Chemistry in a Bag lab. We made of video of what we did and wrote down our results.
