At the stem group today we are going to be looking at Red Cabbage indicator.

I have prepared some solutions we can test, Jess, one of the librarians had prepared some red cabbage indicator for us.

This uses a different preparation method, but the result is the same, a universal indicator.

So we will be undertaking this at Paignton Library, in room 12, as this is more suitable, has sinks, running water etc.

Some of the items we can test include:-

• Tap Water
• Bicarbonate of soda solution (known concentration)
• Citric Acid (known concentration)
• Lemon Juice
• Lime Juice
• Sodium Carbonate Solution
• White Vinegar
