Phosphoric acid (H3PO4) is used in the production of phosphate fertilizers and is often found in soft drinks (check the labels). In the molecule, phosphorus is at the center, and the hydrogen atoms are attached to the oxygen atoms. Phosphorous acid (H3PO3) differs slightly in that one of the hydrogen atoms is attached to the central phosphorus atom. Select the Lewis electron dot structure of both.
Compare the formal charges on the phosphorus atoms. (Write your answers using the format +1 and -2.)
