In this lab we tested calcium, phenol red, sodium bicarbonate. Phenol was red liquid and calcium was a bead like powder and the sodium was a whit powder. The testings went in this order all to gather for the first tes and the bage was oragne smelled like Rubbing alcohol, and it was warm. The second test was calcium with red and it was pink and smelled like rubbing alcohol, third was sodium and water it was hot. The fourth was red and sodium it was very hot, the fifth one was calcium and water, it was cold. The sixth experiment was calcium and sodium and red and it was hot and orange. The next is the seventh and final test and it was calcium, sodium and water, it was hot for a little bit and did nothing else's it was white.
1.due to the experiments tests I would say that either the phenol red or the water Is responsible for the heat and or temperature change.
2.in the individual tests their was an temp. Change and it was due to either water or phenol red. One the tests turned out to have a cold temperature.
3.the color change in the tests were due to the phenol red mixing with other substances like calcium and water.
4.usually i see both a the same time but i think that the color would come first.
5.i think that the water played a big part in the chemical change in the expirements
6.the chemicals responsible to the change in substance is red and water and sodium bicarbonate.
7.the expire,ent would be like mixing them together and it wouldnt change for and it would heat up
8.sometimes thats what i look for when i am conducting and expirement.
