book Water-Palmer.. figure 13

[rodrigoschuch]

Hello folks!

I have a question about water:

This is my water profile:

Ca: 3.6 ppm
Mg: 2.7 ppm
Na: 6 ppM
Chloride: 9.2 ppm
Sulfate: 13.4 ppm

Bicarbonate: 22 ppm
Total alkanility: 19.3 ppm as Caco3
Ph: 6.4

My question: In the palmer water book, there is a table showing the percentage of carbonate species according to the ph .. and at pH 6.4 we have approximately 51% bicarbonate and 49% carbonic acid.

I know that having the parameters of alkalinity and pH, it is possible to estimate the amount of bicarbonate. But how can I interpret these propotions?

That's some pretty soft water so your percentages won't make a significant difference since the numbers are so small to begin with. Post this in the Brew Science forum. Martin and AJ can answer this and any other question you have on chemistry. They have a wealth of information.
