Chemistry in a Bag

The first thing we had to do was gather all of our items. We got one scoop of calcium choride, one scoop of sodium bicarbonate, one pipet of phenol red, and one pipet of water.

OBSERVATIONS:

Calcium chloride- solid white pebbles

Sodium Bicarbonate- white fluffy powder

Phenol Red- Red liquid

Water- was a clear liquid

Steps: On video.

Post lab questions.


1. Phenol red with the calcium chloride or water with the calcium chloride.


2. Yes phenol red and sodium bicarbonate turns cold.


3. It turned orange. And so did many of the others that we tested.


4. No. The color changes first then the gas bubbles appear and then temperature change.


5. Our group used calcium chloride and sodium bicarbonate mixed together and nothing happened. Phenol red reacted with both of the non-liquid variables.


6. All of the variables except phenol red need to be included to produce gas in this expiriment.


7. Let all of the water evaporate and see if the calcium chloride is still in the bag.


8. I don't believe it does because the temperature change could be caused by the shaking of the bag.
