2.29: Understand How to Use the pH Scale, From 0-14, can be Used to Classify Solutions as Strongly Acidic (0-3), Weakly Acidic (4-6), Neutral (7), Weakly Alkaline (8-10) and Strongly Alkaline (11-14)

UNIVERSAL INDICATOR: Solution or paper indicator that changes into a range of colours to specifically identify pH of solution

s

In Solution form, drops of Indicator is added and colour change is observed
In Paper form, paper is dipped into solution and colour change is observed
