Red Cabbage Juice Ph. How will boiling red cabbage produce a ph i hypothesis: What is it about cabbage that causes this to happen?

Colour of filter ^ materials: Used an indicator solution called phenolphthalein. Pour the mixture through a strainer into a large container.
We Began The Lab By Pouring 100 Milliliters Of Red Cabbage Juice, Which Was Made With Distilled Water, Into A Beaker.
Using the ph probe provided for the lab, we set it in the solution for one minute, and the result was that the solution had a ph of 6.6. Red cabbage juice is a good indicator of ph because it contains flavin, a pigment molecule that changes colors according to the concentration of hydrogen ions in a solution. How will boiling red cabbage produce a ph i hypothesis:
The Pigment Turns Red In Acidic Environments With A Ph Less Than.
This part of the project requires chopping and cooking. Put the red cabbage leaves into the blender with 800ml of water. Pour the mixture through a strainer into a large container.
When You Begin To Test The Ph Of Other Liquids, The Juice Will Change Different Colors If It Is Mixed With An Acid Or A Base.
Making the ph indicator (this can be done in advance): Cover the cabbage and turn on the food processor until the cabbage is fully blended. Remove the strainer and set aside.
This Is Your Ph Indicator!
Make sure you have an adult to help before you begin! The pigment turns red in acidic environments with a ph less than. Place a strainer over a bowl and dump the blended red cabbage into the strainer.
Colour Of Filter ^ Materials:
Lewis acids and what separates strong and weak acids/bases (mo 3.2). The reason the red cabbage dye turns green at high ph values is due to another pigment molecule, an anthoxanthin, which is colourless until high phs, when it turns yellow. Red cabbage juice is considered to be an indicator because it shows us something about the chemical composition of other substances.
