On Tuesday we did an experiment with coke. we put the coke into a beaker and let it simmer for a while, once it boiled up we collected the vapor into a test tube to make fresh clean water. The way we did that was we set up a tripod and put a bunsen burner underneath the tripod. Next, we put the gauze on top of the tripod. After we that we put the beaker on top then poured the coke into the beaker to let it steam up.

Equipment:

tripod

beaker

bunsen burner

test tube

gauze mat

boss head and clamp

retort stand

Ans: The boiling points of the liquid are different.

2. What are the two chemical processors happening during the reaction?

Ans: Vaporization and 

3. How is distillation used in real life? Name some examples.

Yesterday we used potassium permanganate by putting it into 6 different test tubes. In the first test tube, we put 10 ml's of water in the remaining 5 test tubes we put 5 mil's of water. We used tweezers and added a single crystal of potassium permanganate to test tube one. We gently shook the test tube until the crystal dissolved. Next, we used a pipette and took 5 ml's from test tube one and poured it into test tube 2. We repeated this with all the test tubes until we got to test tubes 6.

our result was diluting the potassium permanganate so the last test tube was considerably lighter in color compared to test tube one. I found out that concentration is a strong form of liquid and dilution is a watered down version of a liquid.
