Phosphoric Acid Complete Neutralization

概述

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.
