Iodine Clock Reaction
Purpose: The purpose of doing this experiment is the see if we can make a chemical reaction in under 2 minutes. My goal of running these experiments were to see if my team and I can get the chemicals to change within a minute. Procedure: We were able to get close to a minute the second time around by changing the temperature of both liquids, for the A cup we put it in the microwave for a minute and the B cup we put in 3 ice cubes. And then when we mixed them together the chemicals reacted faster and and it changed in just 1 min and 10 secs. The 3 rd time we did it we just put the A cup in the microwave for 30 secs and kept the B cup at its normal temperature, and it changed in 1 min and 45 secs, so time went up 35 secs.
In your own words, define the following chemistry terms:
Element: a component or constituent of a whole or one of the parts into which a whole may be resolved by analysis.
Chemical reaction: chemistry, reaction.
Atom: energy, this component as the source of nuclear energy.
Proton: a positively charged elementary particle that is a fundamental constituent of all atomic nuclei.
Neutron: an elementary particle having no charge, mass slightly greater than that of a proton, and spin 1/2: a constituent of the nuclei of all atoms except those of hydrogen.
Electron: electricity, a unit of charge equal to the charge on one electron.
Write the chemical formula for the following substances:
Vitamin C: C6H8O6
What variable did you change during your trials? Why did you choose this variable?:
We changed the temp because, we thought the chemicals would have a faster reaction for the chemicals to change.
Was there a linear relationship between the change in your variable and the change in your times? If not, what type of relationship was there?:
Changing the temp actually worked out really well because, are lowest time was 1:10.
Based on your experiences, what are some ways to speed up a reaction? What are some ways to slow down a reaction?
The best way to make the reaction speed up is to change the temp in both before you mix it together.
Conclusion: The closest time me and my team got to 2 mins was 1 min and 45 secs. So we didn't react our goal of 2 mins but at least we got pretty close to our goal.
