Hoping someone in here may be able to offer some insight as to how to calculate for the use of H3PO4 in my water. Ideally, I am looking for suggestion on which formulaes to modify in the EZ Water spreadsheet and how (with what values).
I do not have any Chemistry in my background. Not even High School. But I can be taught so, please help a brother out.
Ca = 45
Mg = 23
Na = 114
Cl = 118
SO4 = 194
HCO3 = 65
pH = 9.3
I employ a Hannah pH meter for use on brewday and usually add the salts before I check pH. I noticed when playing with HCl in the spreadhseet above that even a small amount changes RA quite signifigantly. Not sure if Phos Acid has the same effect or not.
I am using Phos because I also adjust the pH of my sparge water to pH 7 and I find that so much Lactic or Citric Acid is required that it imparts a sourness to the water that I am trying to avoid.
