It would take many pounds of baking soda to neutralize one gallon of Muriatic Acid -- roughly around 8 pounds plus a lot of carbon dioxide outgassing. For pH Up, it would be roughly 5 pounds. I would not dump the resulting mixture in the pool since the actual affect on the pH would be dependent on the amount of carbon dioxide outgassing and that's not very predictable. The result is basically salt water with very high Total Alkalinity and probably a somewhat high pH (around 9 or so). In 10,000 gallons it would probably increase TA by 7 ppm, salt by around 60 ppm and raise the pH a little (a few tenths), but again, this isn't very predictable and would only work this way if the acid and baking soda were mixed outside the pool since it assumes a lot of carbon dioxide outgassing (if added directly to the pool separately, the outgassing would be much slower and your pool water would be more acidic -- probably around 6.5 in pH).Sportsman said:fascinating. After reading threads on storing MA, I debated what to do my left over for the winter. It's cheap enough locally to just neutralize a gallon and not worry about storage over the winter. Of course, I dont know how much baking soda it would take to neutralize a gallon and the process of dilute/soda/repeat could be a pain.
Do you dump the neutralized in the pool or down the drain? Does it matter?
Make sure the container is U.V. stable, seen too many cases where containers have degraded under U.V.chem geek said:Acid keeps really well so there's not really a need to get rid of it. Just store it away from metal. One could keep it outside -- just have it in a well-ventilated area.
