Archetype Sub-90 Dry-Wipe Invariant (Strong Acid Factor-of-10 pH Dilutions, Weak vs. Strong Acid Foils & Salt Preparation Methods): Every 10-fold increase in total volume V_final / V_initial = 10^k increases strong acid pH by +k units (capped at pH 7). To shift pH by +k, you must add (10^k - 1)*V_initial of water.
