Organic is something has been living. An example of this is compost; a manure used in gardening and worm farms. Compost is derived from soil, and fruit and vegetables scraps.
Red cabbage is used as an organic indicator. It will change colour in acids and bases.
Method:
1. Put a couple of drops of each test sample onto a spotting tray.
2. Add a couple of drops of red cabbage juice, and note the colour.
Results:
Mandarin colour: It turned a dark red colour = N/A
Lime colour: It turned a light pink colour = acid
Apple: It turned a different, lighter shade of purple = neutral
Handy Andy: It turned green and really bubbly = base
Liquid jif: Turned a lighter shade of purple = neutral
Lemonade: Turned a very light shade of pink = acid
Sodium hydroxide: Turned light green = base
Sulphuric acid: A light shade of pink = acid
Note: Acids and bases can be dangerous.
