I learned that things can change color baced on weather it is asitic or basic by mixing it with a nutrual substance (in our case it was cabbage solution) . I thought it was pretty cool.
The lab was pretty entertaining to be honest. But what I learned from the lab was that bases and acidic substances turn cabbage juice different colors :)
