with C_T back-calculated from the measured alkalinity and the water's pH,
and f the carbonate speciation from carbonateProtonsDonated; the
[H⁺] and [OH⁻] terms are dropped, as in totalCarbonateMMolPerLitre. The
acid's own equivalents are then evaluated at the target pH, so a phosphoric
dose isn't costed as one equivalent per mole.
Sparge water above about pH 6 strips tannins and silicates out of the husks
as the grain bed's own acidity washes away. Below 5.2 there's nothing more to
gain and the runnings start to taste sharp.
Acid needed to bring water (typically sparge water) to a target pH.
Straight carbonate titration, no malt involved:
