Best Answer

Because it can identify the basicity or the acidity of the whole pH scale. This includes right from 0-6, acidic, 7, neutral, and 8-14, basic. This is colour coded, using warm colours, red, orange and yellow to indicate acids. It uses green to signify neutrality and uses dark greens, blues and purples to indicate basicity.

It covers the entire range of potential pH values, so it is an indicator that is universally applicable to solutions for finding pH.
