Thanks, it does help. One more question. If one uses this to precipitate out the calcium, does one get water that is high in sodium chloride? This would create a whole other problem... and perhaps a more serious one for someone trying to control their salt. Thanks again. PT

Sodium bicarbonate (baking soda) and sodium carbonate (washing soda) are both highly soluble in water When you heat baking soda above 70 c , it looses on e carbon dioxide (NaHCO3 -> Na2CO3) , ignore stoichiometry for now, and it becomes washing soda. When you add this to water containing Calcium (probably Calcium Chloride) they swap parts and the resulting Calcium carbonate precipitates out of solution and you get de-calcified water. Sodium Carbonate + Calcium Chloride ->Sodium Chloride + Calcium Carbonate hope that helps. regards hg PT Ferrance wrote: I'm confused.
