Feb 14, 2012 · The lab measures and reports alkalinity as CaCO3.They do not report CaCO3. This is bad enough. The spreadsheet authors are cognizant of the fact that there is in fact very little carbonate in a typical sample as most of it has been converted to bicarbonate and so thought it would simplify things (reduce confusion) if they dealt with alkalinity as bicarbonate.

Apr 21, 2020 · 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.

May 27, 2010 · 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...

Dec 5, 2012 · This says HCO3 is 60.96% of the mass of CaCO3. The titration test for these is the same, using Sulfuric Acid. Using a test value from the annual report of 189.3 ppm(mg/L) Total Alkalinity… 189.3 X 0.6096 = 115.40 mg/L (ppm) as Bicarbonate ion (HCO3) in City Water."

Nov 18, 2020 · 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 that reduce the good stuff like Mg etc. too?) 2.

May 28, 2017 · 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 brew saisons, and an all wheat saison at that. Previously I just bought an 80/20 mix of dH2O and spring water and called it good. Efficiency was marginal at best despite LONG step mashes.

Aug 24, 2017 · HCO3: 291.0 SO4: 25.0 Cl: 92.0 Alkalinity as CaCO3: 239 For the mash, I was thinking of doing nothing but adding in some gypsum to get SO4 and Cl at rough equity. For the sparge, I was thinking of doing 50:50 my water and RO, …

Jul 4, 2023 · alkalinity, and you can pick either "mg/L HCO3" or "as CaCO3". You can calculate one from the other, though like I already said, strictly speaking you should also know the pH, but it doesn't matter all that much. My software actually asks for it in mEq/L [and pH], which I find to be a unit that I can wrap my brain around. I guess I don't like ...

Feb 23, 2019 · 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. Normal Weight = Molecular weight/(absolute value of Valence) Normal Weight of CaCO3 = 100/2 = 50 Normal Weight of HCO3- = 61/1 = 61 61/50 = 1.22

Sep 1, 2020 · The weird thing is the software isn't showing any big amounts of wrong values (except the HCO3): The pH with my water treatment and malts is 5.59, I could add 4.1ml of lactic acid (concentration 80%) this will lower the pH to 5.30
