Step-by-step explanation:
The pH scale is a scale from 0 to 14 that shows how acidic or alkaline a substance is. A pH of under 7 is considered an acid and the closer the number is to 0 the stronger of an acid the substance is, however if a substance has a pH of 7 then it is considered to be neutral. When a substances pH is above 7 it is considered alkaline and the closer it is to 14 show how alkaline the substance is.
A universal indicator shows you the pH of a substance using a spectrum of colours, that represent the numbers from the pH scale.
