Neutralizing Phosphoric Acid - Chemical Forum
I’m using phosphoric acid (H3PO3) to clean cement off some brick pavers and I’d like to neutralize it with either bicarbonate of soda (NaHCO3) or quicklime (CaO) before washing it into the soil. I read on the net that because phosphoric acid has 3 hydrogen molecules and bicarbonate of soda has 1, I therefore need to use three times as much bicarb to neutralize the acid.
