What happens, do some not dissolve?
Most salts will dissolve (with the exception of CaCO3 if the water becomes super-saturated for its pH). It wasn't my intention to be confusing when I said that your water profile is electrically unbalanced - what I meant is that the numbers that you posted here can not actually exist in real water with a reasonable pH. Your water does not correlate absolutely to the numbers for mg/L of ions in your water because it cannot.
Do you remember in chemistry when you'd have to balance a molecule based on its constituent ions electrical charge? That is electrical balance. All water has a neutral electrical charge - therefore every positively charged cation must have an equally negatively charged anion - that's why the formula for calcium chloride is CaCl2 and not CaCl - because Calcium must loose two electrons to achieve a full valiance shell of 8 e- and therefore has a positive charge of 2 (that's why I've been noting Calcium as Ca++). Chlorine, on the other hand, must gain an electron to have a full valiance shell of 8 electrons - and since electrons carry a negative charge that means the ion will carry a negative charge of 1 (since it has gained 1 electron [it's like adding -1 to 0 - you end up at -1 - think of loosing and gaining electrons as adding and subtracting negative numbers). All electrically neutral molecules must have a sum charge of 0 - therefore, since calcium carries a charge of positive 2 and chlorine carries a charge of negative 1 it takes twice as many chlorine ions to electrically balance 1 calcium ion. Water is like that only it's a whole bunch of those cations and anions. Examples of cations in water are calcium and magnesium while chloride and sulfate are anions. the total electrical charge of these ions must equal 0.
Your actual physical water (if we were able to perfectly measure all of its constituent anions and cations) is balanced - the numbers that you posted here as your water report are not balanced.
Water is like Descartes - it exists therefore it is electrically balanced. Starting with the numbers on the water report that you posted will give you a profile that is not "real" water on any spreadsheet because you are starting from something that is unbalanced and almost no spreadsheets out there test for electrical balance before they allow you to adjust your unbalance profile.
Nothing will happen, but you aren't brewing with the water that the spreadsheet has calculated. AJ Delange has a spreadsheet on his site that accounts for balance within a solution (and notifies you of imbalances with regard to atmospheric pressure and CaCO3 super saturation). That's the spreadsheet I typically use when looking at water. It's the Nearly Universal Brewing Water Spreadsheet available at http://ajdel.wetnewf.org:81
- I'd recommend reading the entire manual for that spreadsheet, available on that site - it's not the most intuitive spreadsheet in the world.
