Question

what is the difference between pH scale and universal indicator?

Answer 1

Explanation:

Universal indicator and the pH scale

Unlike litmus, universal indicator can show us how strongly acidic or alkaline a solution is, not just that the solution is acidic or alkaline. This is measured using the pH scale , which runs from pH 0 to pH 14. ... In the middle, neutral pH 7 is indicated by green.

Answer 2

By using ph scale we can determine whether if the compound is acidic then at what extent and if it is basic what is its magnitude
But litmus onlya can determine whether the compoung is acidic or basic
