Change if something is acidic or basic

9

Example of an indicator

Litmus paper

10

Colours on the indicator to tell if something is acidic basic or neutral

On litmus paper after testing
Blue = Base
Red = Acid
No change = Neutral

11

What does universal indicator do

Will tell if a substance is acid/base/neutral and its PH strength

12

What does the PH scale do

The PH scale tells us how acidic or basic a solution is.
It allows us to quantify (put a number on) a solution

13

Numbers on a PH scale

Grater than 7: alkaline
Less than 7: acidic
7: neutral

14

How can the ph solution be found

A ph meter
Universal indicator solution
