Morphology

theory + of + indicator

The phrase is a straightforward noun phrase formed by 'theory' + 'of' + 'indicators', so a learner who knows 'theory' (set of ideas) and 'indicator' (a chemical showing change) can infer it means the theoretical explanation/about indicators (how they work to show pH). The compositional pattern 'theory of X' is common and cross-linguistically transparent, though the precise chemistry details remain domain-specific.

Etymology

Theory of indicators comes from a simple picture: an indicator is a dye that can be in two forms, each showing a different color in an 'acidic' or 'basic' liquid. So this 'theory' explains why the dye changes color to 'show' how acidic or basic a liquid is.
