The object will change the colour when we place them in pH scale
Then we can check that it is acidic or basic
Acidic-It changes blue to red
Basic-It changes red to blue
Neutral-Yellow
If the pH value is below 7 it is acidic,
If pH value is above 7 it is basic
if pH value is 7 it is neutral
hope it helps
