1. Engineering Principles & Mathematical Formulation

Calculates exact ionic concentrations of Hydroxide, Carbonate, and Bicarbonate alkalinity species in mg/L as CaCO3 from Phenolphthalein (P) and Total (M) alkalinity titration results.

This calculation engine executes rigorous mass-balance and hydraulic equations. Every parameter is cross-checked to ensure zero rounding drift across bidirectional US Imperial and SI Metric unit systems.
