Archetype Sub-90 Dry-Wipe Invariant (Multi-Step Acid-Base Back-Titrations, Diprotic Ratios (H2SO4/Ca(OH)2), Thermometric Titration & Purity): Work in millimoles (mmol = c [mol dm⁻³] × V [cm³]) throughout! Proton-balance law: (# of H+ in acid) × c(acid) × V(acid) = (# of OH- in base) × c(base) × V(base). Always multiply aliquot moles by (V(flask) / V(pipette)) at the end.
