Phosphoric Acid Complete Neutralization

H3PO4 + 3NaOH → Na3PO4 + 3H2O

개요

Complete neutralization of triprotic phosphoric acid requires three equivalents of sodium hydroxide, producing trisodium phosphate (TSP). The resulting solution is strongly basic because the phosphate ion is a moderately strong base. TSP was once the workhorse of industrial and household cleaning.
