Step 2. Add 20 drops of orange juice from concentrate and stir.
Step 3. Repeat steps 1&2 for the orange juice not from concentrate and orange
Step 4. Compare colors and write results. A dark solution indicates low levels of Vitamin C while a light solution indicates high levels.
RESULTS
Based on my experiment data, my hypothesis was correct. The orange flavored drink was the darkest and brightest when mixed with indicator; therefore, it had the least Vitamin C. This was most likely due to the added sugars and artificial flavoring.
The orange juice from concentrate hat the most Vitamin C while the orange juice that was not from concentrate had darker that the juice for concentrate and lighter that the orange flavored drink. Therefore, it had less vitamin C than the juice from concentrate, but more than the flavored drink. Below are a graph and chart that reflect the provided data.
