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.

Phosphoric acid | National Pollutant Inventory
Phosphoric acid is a corrosive acid that can form three different classes of salts, namely primary phosphates, dibasic phosphates and tribasic phosphates. Phosphoric acid is soluble in water. It is incompatible with strong caustics and it is corrosive to ferrous metals and alloys.
home experiment - Citric acid chelates calcium …
I performed an experiment using egg shells (calcium carbonate) to represent teeth and reacted the calcium carbonate with acids. When measuring the rate of reaction citric acid had a higher rate of reaction and from my research I saw that citric acid forms a more stable compound with calcium hence it chelates the calcium more than ethanoic acid.
