Chemistry In A Bag

Materials Needed: Pippett, Pheynol Red, Baggie, Calcium Cloride, Spoons, Cups, Water, Baking Soda, Goggles.

Calcium Cloride. Sodium Bicaribate. Baking Soda. And Phenol Red. :
Temperature: First was really hot, then immediately got cold.
Feeling: I could feel the calcium cloride then it all turned to liquid.
Smell: Smells Like Candy. Smells Sweet
Color: I saw some pink/purple. Then It turned to all yellow.
When I closed it, I made sure I had all the air out of it. Then it started filling up with the gas. It popped at the top so all the air/gas came out.

Baking Soda, Water:
Temperature: Cold
Feeling: Liquidy
Smell: No sent
Color: Milky White.



Baking Soda. Pheynol Red:
Temperature: Not too cold. Not too hot.
Feeling: Liquid
Smell: A Chemical
Color: Purple/Pink

Baking Soda, Pheynol Red & Calcium Cloride:
Temp: Cold
Feeling: liquid

Smell:
Paint

Color: first was pink/purple. then yellow

Water, Baking Soda, & Calcium Cloride:
Temp: Cold
Feeling: Liquid after the calcium cloride turned into liquid
Smell: Paint
Color: Milky White
The Calcium Cloride & the water released Co2 so the bag inflated

Pheynol Red & Calcium Cloride:
Temp: Hot
Feeling: I can feel the beads of the calcium cloride
Smell: Paint
Color: Yellow & Red
It got super hot right when the liquid touched the calcium cloride



Lab Questions:

1.) I think that the calcium cloride made the temperature change in every reaction that it was involved it.

2.) Calcium Cloride & Pheynol Red produced the heat.

3.) In the overall reaction it was all pink & purple then it started turning yellowish orange when I kept shaking it. The Pheynol red & the calcium cloride changed the color.


4.) No, because the baking soda & the water caused the Co2 and it didnt have a temperature change.

5.) All were tested.

6.) The changing of the temperature, color, feeling, and smell make a new chemical substance.

7.) See what changes after you combine calcium cloride & water.

8.) Yes, temperature changes are caused by the breaking chemical bonds & forming new ones then that makes a new chemical creation.
