purple cabbage

Today in science we are doing a purple cabbage experiment.

I was working with my friend Addyson

here is our document we had to fill out and it will tell you a little bit of information.

What colour do you think the white vinegar will turn the purple cabbage indicator? Light purple pink
color

Why do you think this? Because the vinegar is strong and it might get rid of some of the color.
Depends on how long the cabbage is in vinegar for.

What colour do you think the washing powder will turn the purple cabbage indicator? Dark blue

Why do you think this? Because it's not as strong as the vinegar so it might make it darker.

Method:

1 Peel off three or four big cabbage leaves and put them in a blender filled half full with water.
Blend the mixture on high until you have purple cabbage juice.

2 Pour the purplish cabbage liquid through a strainer to filter out all of the big chunks of cabbage.
Save the liquid for the experiments to follow.

3 Set out three beakers, side by side. Fill each glass three-quarters full with cabbage juice.

4 Add a little vinegar to the first beaker of cabbage juice. Stir with stirring rod and watch the colour
change.

5 In the second beaker, add a little laundry detergent and stir.

6 Take a photo of your 3 beakers side by side.

The one with vinegar turned light purple and the one with washing powder turned blue.
