  • HCO3 = CaCO3? - Homebrew Talk
    My water report lists "bicarbonate as CaCO3" but BeerSmith is asking for bicarbonate as HCO3 Can one derive the former from the latter? Does any of this really matter since apparently I should be using EZ Water calculator? Also, is the convention to use averages when determining the constituents of one's water?
  • Very high bicarbonate in water, what to do? - Homebrew Talk
    Hi all, I just got a water analysis from the town council and entered the numbers into my software It turns out that the HCO3 level is 397ppm As I understand, that reduces the drop of PH while mashing what else I've learner's is that a can 1 Dilute the water with distilled water (but won't
  • Adding baking soda to the kettle to achieve HCO3 target?
    Since there really isn't a beer style HCO3 ppm target, the purpose of baking soda, or any source of HCO3, is solely to raise a low mash PH to the ideal mash PH - typically only needed for dark styles The amount of baking soda added to the mash should be based on what is required to hit the target mash PH
  • Reducing HCO3 - Homebrew Talk
    I'm from Galveston Texas I have two broad questions, but bear with some background information first: 2016 Water report: Ca 2+ 37 Mg 2+ 7 HCO3 - 127 SO4 2- 38 Na + 37 Cl - 51 pH 8 1 (their measurement) pH 7 (my presumably much less accurate measurement at the faucet) I only
  • alkalinity as CaCO3 - Homebrew Talk
    This assumes that HCO3- has one alkalinity equivalent and that CaCO3 has 2 alkalinity equivalents As a result you mulyiply [HCO3-] with 50 and divide by 61 The result is 0 5ppm alkalinity as CaCO3 But there is a problem The actual alkalinity contributed by CaCO3 was not one equivalent but 2
  • Bicarbonate from Total Alkalinity - Homebrew Talk
    To quote him from an email: "HCO3 (bicarbonate) is a fractional part of CaCO3 (units of the total alkalinity), by means of the molecular weights 100 086 to 61 016 (61 016 100 086 = 0 6096) This concerns mass units only This says HCO3 is 60 96% of the mass of CaCO3 The titration test for these is the same, using Sulfuric Acid
  • Total Alkalinity, CaCO3 as a function of Bicarbonate, HCO3
    My most recent Lab Wards report shows my Total Alkalinity, CaCO3 as 89, my Bicarbonate, HCO3 as 97 and my pH as 8 1 I had read that for pH under 8 3 Total Alkalinity, CaCO3 = 50 61 * Bicarbonate, HCO3 That does not hold true for my numbers My report also lists Carbonate, CO3 as 6 Does
  • Total Hardness vs Alkalinity - Homebrew Talk
    bicarbonate == HCO3, so take a wild guess ;-) Alkalinity "as CaCO3" is a fictional unit and means how much alkalinity you'd get if you added that much CaCO3 If you add for example potassium carbonate (K2CO3), you'd still get "alkalinity as CaCO3", but you wouldn't have added any CaCO3
  • PPM Calculations - Homebrew Talk
    I was in a hurry when I wrote No 2 and so was rather terse If you add 1 mmole of sodium bicarbonate to a liter of deionized (DI) water 0 98 mmol stays as bicarbonate, 1% converts to carbonic acid and 1% converts to carbonate If the water has any alkalinity and the pH is lower than 8 38 the acid in it (HCO3- ion) will pull the pH of the mix lower and more of the bicarbonate will convert to
  • brewing with very hard water - reducing bicarbonate
    HCO3- has a 'rounded' molecular weight of 61 and a valence of -1 CaCO3 has a 'rounded' molecular weight of 100, and its cation and anion components have valences of +2 and -2 respectively
