- End mixture is clear.
- End mixture is 29oC.
Experiment - It cooled by 30C.
Experiment F
- Water is clear, sodium polyacrylate is white.
- The mixture is a solid, opaque substance that sticks to the beaker.
- The sodium polyacrylate absorbed all of the water.
- It is a jelly like substance hat looks like ice.
Conclusion:
The purpose of the lab was to identify physical and chemical changes through different experiments. We achieved this purpose by performing 6 different experiments and determining weather or not it was physical or chemical. Experiment A was a physical change because mixing water and copper sulfate gave a blue liquid, boiling away that water left a white powder, and adding water back turned it blue again. Experiment B was a chemical change because adding a magnesium strip to HCI caused it to dissolve the strip and had an exothermic reaction. Experiment C was a chemical reaction because mixing water, Epsom salts and ammonia created a
