  1. Solubility on Cough Drops By: Wendy, Jennifer J, Kamrul

  2. Why we chose this for our experiment ? • Probably everyone wondered at least once, why do halls dissolve in our mouths. Here we will show our step by step process of our experiment and show why some things dissolve faster than others? • We will use halls for our experiment.

  3. What is Solubility ? Solubility - In general, solubility is a substance that dissolve. In the process of dissolving, the substance which is being dissolved is called a solute and the substance in which the solute is dissolved is called a solvent. A mixture of solute and solvent is called a solution. .

  4. Materials • Water (hot and cold) • 5 cups of the same size • a marker to label • 5 cough drops (halls mentho-lyptus) • A thermometer to take the waters temperature • A balance to weight the halls after being in the water

  5. Methodology • First we bought 5 of the same cups and for each cup we added hot and cold water and mixed them up so that each cup had a different temperature of water. • After that we labeled each cup from 1 to 5 with a marker. • Next we took each cup of water its temperature (each cup of water needed to have a different temperature so our experiment would collect data) • We next dropped a halls in each cup at the same time and left it there for 20 minutes to see how much mass would have been lost. • Now that the 20 minutes are up we take out each halls out of their cups and put them to dry so the water doesn’t make it really sticky. • Next we weight each of them on a balance and see how much mass each of the halls lost. • And now we collect all our information and we graph.

  7. Graph increasing temp decreases solubility

  8. What could’ve been different? • We could’ve tested it a few more times since it was a short experiment. • Be able to use more cups so that there would’ve been more data.

  9. Conclusion • In conclusion the highest temperature was the one that made the halls dissolve faster then the one that was at room temperature. • Overall it was an exciting experiment and we learn many things.
