Chemistry in a Baggy

Chemistry in a bag. we used phenol red, calcium chloride, sodium bicarbonate, and water.


the calcium chloride looks similar to dip n dots, it is white, and very clumpy. Sodium Bicarbonate is white and looks similar to flour. and phenol red is a dark red liquid substance with a very low viscosity. Then we mixed one scoop of calcium chloride, one scoop of sodium bicarbonate and one pipet of phenol red and one pipet of water. Then we allowed all the chemicals to mix, and started to Observe the observations.

Observations of test 1

• the temperature didn't change at first


• the bag started to inflate


• it turned yellow


• smelled like rubbing alcohol

Observation of test 2

We used everything but water

• Pink not doing anything


• looks like sand


• dryed out


• smells like rubbing alcohol

Observation of test 3

We used water, phenol red, calcim chloride

• Hot


• pink


• no gas production


• smell-alcohol

Observation of test 4

• we used baking soda,and calcium chloride


• it started to get cold


• it smelled like rubbing alcohol

1. i beleave that it was phenol red and calcium chloride that mixed and cause the temperature change.

2. yes, some were colder then others

3. the colors were mostly pink then changed to yellow if you did the experiment right

4. yes, because the chemicals that mixed may be causing the color and the bubbles.

5. usuall no because water doesnt do anything

6. calcium chloride and phenol red and baking soda

7. add something diffrent

8. not always because some chemicals can change but it stay the same temperature.
