10 values, each with its units, its uncertainty, and where it came from.
All 361 constants →
kg/molThe equivalent weight of caustic soda, 39.997 g/eq — identical to NaOH's formula mass, because each unit supplies exactly one hydroxide.
kg/molThe equivalent weight of citric acid, 64.041 g/eq — a third of the 192.123 g/mol molar mass, counting all three carboxylic protons.
kg/molThe equivalent weight of hydrated lime, 37.046 g/eq — half of Ca(OH)₂'s 74.092 g/mol, two hydroxides per formula unit of slaked lime.
kg/molThe equivalent weight of hydrochloric acid, 36.458 g/eq — equal to its molar mass, since the molecule has exactly one proton to give.
kg/molThe equivalent weight of nitric acid, 63.012 g/eq — identical to the molar mass because HNO₃ is monoprotic, one proton per molecule.
kg/molThe equivalent weight of phosphoric acid for alkalinity work, 97.994 g/eq — one proton counted, since only the first titrates by pH 4.5.
kg/molThe equivalent weight of soda ash, 52.994 g/eq — half of Na₂CO₃'s 105.988 g/mol, since carbonate accepts two protons on the way to CO₂.
kg/molThe equivalent weight of sodium bicarbonate, 84.006 g/eq — the whole formula mass, one proton accepted, the gentlest alkalinity feed.
kg/molThe equivalent weight of sodium bisulfate, 120.054 g/eq — the full formula mass, one acidic proton, the workhorse of dry acid dosing.
kg/molThe equivalent weight of sulfuric acid, 49.036 g/eq — half the 98.072 g/mol molar mass, because each H₂SO₄ delivers two protons.
