1. Rose with Aluminum Potassium Sulfate in two different beakers

One with Acid Tartaric(acid base) and other one with Sodium Bitartrate(alkaline base)

*Rose with Aluminum Potassium only created blue-ish purple

*One added Acid Tartaric created pretty red

*One with Sodium Bitartrate created somewhat between other two

2. Blueberry with Aluminum Potassium

*Created light blue-ish purple while I kinda expected dark purple.

3. Beets with Aluminum Potassium created purple color

4. Leaves of beets + Aluminum Potassium + Cupric Chloride created pure green.

RESULTS.
