4. This is the green color that formed once we poured the hot solution of K 2 C 2 O 4 *H 2 O into the beaker containing FeCl 3 .

5. Brett couldn’t resist from eating the watermelon rock candy...I mean…green crystals!

6. On Day 2 of Experiment 1… Mrs. Males demonstrated how to use vacuum filtration. The ‘vacuum’ sucks up some of the water that surrounds and is absorbed in the green crystals.

7. Brett and I mimicked Mrs. Males instructions on vacuum filtration and applied it to our self-made green crystals. This is what our crystals looked like after vacuum filtration.

8. After drying out our crystals in an oven, this was our final product. Each time an experiment was conducted using green crystals, these are the crystals that were used.

12. Brett heating the beaker and its contents just below boiling point. Titration followed this.

14. Brett is still hungry! He’s still going after that green rock candy!

17. These were our two green crystal samples used in this experiment’s titration.

18. Brett measures 6mL of 6M sulfuric acid in a graduated cylinder.

22. Ashley rinsing the buret with 7 mL of NaOH before titration.

23. After our equivalence point was reached in our first trial, this is the color change that occurred. Adding 40mL of distilled water to the beaker.

27. Ashley allowing distilled water to pass through the ion exchange column and into the beaker of our green crystals. This picture was taken while we were titrating and taking pH to collect data to find equivalence points.

28. After both equivalence points were found, this is what our beaker looked like.
