Indicators/Red cabbage (Science)

Hey everyone, 

This post will be about science, the experiment we did last week since I wasn't able to post it. There was a rotten red cabbage since our teacher left it for days. We can make colour by using Acid and Base. 

Aim: I want to find out how to change colours by using red cabbage with Acid and Base. 

Research:

Method:

Equipment: 

• Test tube 
• Red cabbage
• Beaker 
• Dropper - science
• Test tube rack 
• Stirring rod 
• Acid and Base

Instructions: 

1. Get all your equipment ready. 
2. Get a (rotten) cabbage and put it inside the beaker. 
3. Add a half of a water inside. 
4. Use the stirring rod to stir till the colour gets darker.
5. Place the test tube in the test tube rack. 
6. Add red cabbage inside the test tube by using the dropper. 
7. Use the Acid and Base ( you can add as much as you want to make a colour) inside the test tube with the rotten red cabbage inside. 
8. Make a colour. 

Results: 

 

First of all, the rotten red cabbage did smell but when we added half of a water inside it kinda fade away. At first, it was really fun making those sorts of colours but everyone got competitive when we had to make different colours, a colour that is not the basic. A mixed colour would also count. I feel like we added more Base than Acid. 

That's all for today, I hope you enjoy reading and that's all for today, goodbye:))
