What is the overall result of adding sodium hydrogen carbonate to .4 PPM TDS distilled and then using that water to make CS?

According to those more knowledeable than I on this what you would end up with would be CO2 continuing to exist in the water, both as CO3-- and HCO3-, with no evolution of CO2 at all. Nice idea, but unworkable.
